MyJurnal

The paradental cyst is an odontogenic cyst occurring near to the cervical margin of the lateral aspect of a root as a consequence of an inflammatory process in a periodontal pocket. A distinct form of the paradental cyst occurs not infrequently on the buccal aspects of erupted mandibular third molar, where there is an associated history of pericoronitis. A search of the literature revealed that these cysts had all been reported in relation to partially, newly or fully erupted molars. This report presents one case in which the cyst was noticed to be associated with an unerupted third molar. The histological appearance of the cyst and the gross relationship to the cemento-enamel junction is similar to those typical of paradental cysts reported in the literature. However, the radiographic and clinical appearance of the tooth being unerupted do not tally with paradental cyst and yet exclude the diagnosis of dentigerous cyst. The diagnosis of dental follicular tissue was excluded based on the histopathological presentation. The authors suggested that this case may represent an early form of paradental cyst which in the past may have been dismissed as dental follicular residues and thus, the prevalence of paradental cyst may have been under reported in the literature.

Sains Malaysiana, 2011;40.

Anticorrosion potential of mangrove tannins on aluminium alloys AA6061 in NaCl solution has been studied using potentiodynamic polarisation method and scanning electron microscopy (SEM). The study was carried out in different pH of corrosive medium in the absence and presence of various concentrations of tannin. The corrosion inhibition behaviour of the mangrove tannin on AA6061 aluminium alloy corrosion was found to be dependant on the pH of NaCl solution. Our results showed that the inhibition efficiency increased with increasing tannins concentration in chloride solution at pH 6. Treatment of aluminium alloy 6061 with all concentrations of mangrove tannins reduced the current density, thus decreased the corrosion rate. Tannins behaved as mixed inhibitors at pH 6 and reduction in current density predominantly affected in cathodic reaction. Meanwhile, at pH 12, addition of tannins shifted the corrosion potential to more cathodic potentials and a passivating effect was observed in anodic potentials. SEM studies have shown that the addition of tannins in chloride solution at pH 12 reduced the surface degradation and the formation of pits.

Fulltext Two cases of congenital vallecular cyst: a reminder of the potentially fatal cause of upper airway obstruction in infants

Abd Aziz A, Abdullah AF, Ahmad RA

Malays J Med Sci, 2010 Jul;17(3):68-73.

PMID: 22135553 MyJurnal

Vallecular cyst, a benign yet rare laryngeal lesion, may cause stridor and even life-threatening upper airway obstruction in infants. It can cause apnoea and poor feeding habits, thus reducing the chance of survival. Although laryngomalacia remains the most common cause of stridor in this age group, awareness and a high level of suspicion for this condition can help lead to early management and intervention. Direct laryngoscopy is accepted as the gold standard for diagnostic purposes, and marsupialisation of the cyst is the preferred treatment. We describe 2 cases of vallecular cysts in infants admitted to our hospital where timely diagnoses led to appropriate treatment.

Fulltext Atretic cephalocele - an uncommon cause of cystic scalp mass

Wong SL, Law HL, Tan S

Malays J Med Sci, 2010 Jul;17(3):61-3.

PMID: 22135551

A 6 year-old girl presented with a midline parietal scalp swelling that had been gradually enlarging since birth. Magnetic resonance imaging revealed communication of the cyst with the subarachnoid space through a calvarial defect, with concomitant findings of vertically positioned straight venous sinus and subependymal grey matter heterotopia. A diagnosis of atretic cephalocele was thus made based on these classical imaging findings.

PMID: 22977380 MyJurnal

In an infant presenting with a mass in the abdomen and non-bilious vomiting, duplication cyst needs to be considered in the list of differential diagnoses. Gastric duplication cyst is an uncommon occurrence in children. Diagnosis is based on clinical findings and imaging features. Surgical excision is safe and offers a complete cure. The literature recommends excision even in asymptomatic cases due to isolated reports of malignancy arising in the duplication cyst in later life.

PMID: 25892954 MyJurnal

Hydatid cysts are not endemic in Malaysia and are rarely seen. We hereby report a case of hydatid cyst of the liver in a 55-year-old Chinese-Australian lady who presented with a calcified liver cyst and negative hydatid serology. A liver segmentectomy was performed and revealed a well-circumscribed, calcified liver cyst containing only creamy whitish material without the typical daughter cyst. A histological examination revealed different layers of the cyst wall and the presence of loose, calcified scolices without a daughter cyst. The case highlights the importance of considering hydatid cyst in the differential diagnosis of liver cyst even in non-endemic areas, as the ease of travelling and migration allows the condition to be seen outside the endemic region.

Fulltext Infant with a sudden, large, post-extubation subglottic cyst

Asha'ari ZA, Suhaimi Y, Fadzil A, Zihni M

Malays J Med Sci, 2012 Oct;19(4):84-7.

PMID: 23613654 MyJurnal

Acquired subglottic cyst in infancy is almost always associated with episodes of early life intubation. Most cases typically presented late, usually days to months after extubation. We report a case of a subglottic cyst with different presentation than the norm. This case highlights that subglottic cyst can present acutely, and rapidly enlarging soon after the airway extubation. As the management of a large subglottic cyst can be challenging, a close observation for early diagnosis and intervention are recommended post extubation in the high-risk cases, such as in the premature infant.

Cystic tumor of papillary muscle of heart: a rare finding in sudden death

Murty OP

Am J Forensic Med Pathol, 2009 Jun;30(2):201-3.

PMID: 19465820 DOI: 10.1097/PAF.0b013e31819d9af5

Primary cystic tumors of papillary muscles of the heart are extremely rare. Here, one case of unusual cystic tumor in papillary muscle of the heart in a 37-year-old Myanmar migrant worker has been reported. He came to Malaysia 2 weeks before and one morning was found dead in sleep. Autopsy revealed cystic lesion in the papillary muscle of the mitral valve of heart, which was prolapsing into ventricular cavity. The cyst had white-jelly like sticky mucus material. The cyst was present in papillary muscle with slight invasion in septum area; it was lined by cuboidal-columnar epithelium and contained mucinous contents. There was no evidence of an inflammatory reaction in the cyst and in cardiac muscles. In addition to cystic neoplasm, the deceased also had histoplasmosis of the lungs. The case is presented with macroscopic and microscopic photographs of the cyst and histoplasmosis of the lungs. This case is reported because of its rarity, unique position, and unusual appearance.

Odontogenic keratocyst with dentinoid formation

Ng KH, Siar CH

Oral Surg Oral Med Oral Pathol Oral Radiol Endod, 2003 May;95(5):601-6.

PMID: 12738952

Although rare, hard tissue deposits, namely dystrophic calcifications and cartilage, have been reported to occur in the connective tissue wall of the odontogenic keratocyst. However, dentinoid formation has not been previously documented. A case involving the left mandibular premolar-molar region in a 37-year-old Malay male is described here along with a brief review on the reported prevalence of hard tissue deposits in the odontogenic keratocyst. Differential diagnosis of this case from other dentinoid-forming odontogenic cysts and tumors-notably calcifying odontogenic cyst, odontoma, ameloblastic fibro-odontoma, central odontogenic fibroma and adenomatoid odontogenic tumor that may present with dentin/dentinoid formation-is discussed.

Follicular adenoma with squamous metaplasia and cystic change: report of a case with fine needle aspiration cytological and histological features

Jayaram G, Jayalakshmi P

Malays J Pathol, 1999 Dec;21(2):101-4.

PMID: 11068414

Squamous metaplasia (SM) of thyroid follicular epithelium is known to occur in a variety of non-neoplastic lesions as well in thyroid neoplasms, notably papillary carcinoma (PC). In follicular thyroid tumors, on the other hand, SM is very rare. This case describes cytological and pathological findings in a follicular adenoma (FA) that presented as a cystic lesion with extensive SM. The fine needle aspiration (FNA) cytology sample in this case yielded only necrotic material from the cystic area and squamous cells, which being mostly of immature type, were not recognised as squamous in the cytological smears. The needle missed the solid (neoplastic) component of the lesion and on the whole the cytological picture was considered to be equivocal. FA can now be added to the spectrum of thyroid lesions that can show SM. Awareness of this will enable cytopathologists to consider non-papillary lesions in the differential diagnosis of thyroid nodules that yield squamous cells.

Fulltext Managing the solitary thyroid nodule

Meah FA, Qureshi MA

Med J Malaysia, 1998 Dec;53(4):453-6; quiz 457-8.

PMID: 10971996

Solitary thyroid nodules are commonly seen in surgical outpatient clinics. A detailed history and a careful physical examination are essential. In the management of the solitary thyroid nodule, fine needle aspiration cytology has become the cornerstone investigation. Ultrasound cannot differentiate between benign and malignant nodules, however is useful in the follow-up period to identify any further nodular growth. As thyroid malignancy occurs in both hot and cold nodules, radionuclide scans are not useful in the management of solitary thyroid nodules. We have attempted to outline the process of managing the solitary thyroid nodule and discuss the options available.

Med J Malaysia, 1986 Dec;41(4):365-9.

PMID: 2823084

Carcinoma of the biliary tract is a rare complication of choledochal cysts. Furthermore, the greater predisposition of the cyst wall to neoplastic change has been cited as additional justification for cyst excision rather than on-site internal drainage as the primary choice of operation. The report concerns a patient who developed cholangiocarcinoma despite excision of a choledochal cyst and presented with symptoms of biliary obstruction within one year of the operation. Although this is a rare complication, the need for careful long-term follow-up is supported by this observation.

Jpn J Surg, 1980 Jun;10(2):94-9.

PMID: 6253701

We present a study of 288 hepatic resections carried out in Malaysia for the past fifteen years. First, we describe our indications for hepatic resectins which are not limited to hepatic trauma and hepatomas, but also include hepatic abscesses, cysts, intrahepatic calculi and hemangiomas. Second, we give a simplified classification of hepatic resections using accurate terminology. Third, we describe the safety of hepatic resections in our hands which we believe is due to specially designed surgical instruments and the accurate decision making process at surgery. We have had minimum postoperative mortality and no intraoperative deaths so far. Finally, while analysing each indication we have drawn vignettes from our experience for the past fifteen years.

Anomalous arterial supply to the muscles in a combined latissimus dorsi and serratus anterior flap

Halim AS, Wan Z

Clin Anat, 2004 May;17(4):358-9.

PMID: 15108344

The combined latissimus dorsi and serratus anterior flap has been employed for large defect reconstruction and has been shown to be reliable. These flaps are based on the subscapular-thoracodorsal vascular pedicle that usually supplies both muscles. In the case reported, serratus anterior possessed an anomalous arterial supply totally independent of the subscapular pedicle. The latissimus dorsi and serratus anterior muscles were used as a combined flap to reconstruct a massive thigh defect. The combined flap required two arterial anastomoses.

Fulltext Assessment of fragile histidine triad expression in ameloblastoma, odontogenic keratocyst and dentigerous cyst

Haragannavar VC, Tegginamani AS, Raju S, Kudva S, Peter CD, Shruthi DK

Indian J Pathol Microbiol, 2019 2 2;62(1):3-6.

PMID: 30706851 DOI: 10.4103/IJPM.IJPM_403_18

Background: FHIT (Fragile histidine triad) a member of tumor suppressor family, has been extensively studied in many solid tumors including head and neck squamous cell carcinoma. Among all head and neck cyst and tumors odontogenic lesions account approximately 3%-9%. The molecular pathogenesis of these lesions is less explored. Defects in cell cycle regulators and tumor suppressor genes could result in the development of odontogenic cyst and tumors. Hence, we aimed to determine the significant role of a tumor suppressor gene FHIT in most commonly occurring odontogenic lesions mainly ameloblastoma, odontogenic keratocyst and dentigerous cyst.

Subjects and Methods: Immunohistochemical analysis of FHIT was done in ameloblastoma, odontogenic keratocyst, dentigerous cyst and dental follicle. Interpretation of the stained slides were done using standard scoring criteria by two pathologist. The results were subjected for statistical analysis.

Results: Expression of FHIT varied among the groups, with highest negative expression in ameloblastoma 44.4% followed by odontogenic keratocyst 14% and 100%positive expression was seen in dentigerous cyst. The expression levels between the groups were statistically insignificant.

Conclusion: The varied expression or negative expression of FHIT could be considered as an indicator for aggressive behavior and transformation of preneoplastic/cystic epithelium.

A Challenge in Diagnosis and Management: Uterine Torsion in Childhood

Thever Ramasamy V, Sivapatham L, Grover SR, Shanmugam SS, Ganesalingam M

J Pediatr Adolesc Gynecol, 2021 Feb;34(1):61-64.

PMID: 33010465 DOI: 10.1016/j.jpag.2020.09.003

BACKGROUND: Uterine torsion is a rare event, which mostly reported in females with a gravid uterus and is exceptionally rare in children.

CASE: A 9-year-old girl presented with 3 days of intermittent lower abdominal pain. Ultrasound revealed an ovarian mass, but laparotomy revealed an ischemic enlarged ovary and uterus rotated 180°. No reperfusion occurred after 60 minutes. A subtotal hysterectomy and right salpingoophorectomy were thus performed.

CONCLUSION: Uterine and adnexal torsion presents with symptoms similar to those of adnexal torsion. Delays in diagnosis and referral continue to be an issue, resulting in suboptimal outcomes. Uterine torsion, although exceedingly rare in childhood, appears to occur only in the setting of ovarian masses, which provide the impetus for the rotational force to the elongated cervix of the prepubertal uterus.
