Following its capture in March 2014, an adult female Sumatran rhinoceros frequently showed profuse vaginal bleeding. An ultrasonography suggested the presence of multiple reproductive lesions, including two uterine masses which were suspected to be leiomyomas. Soon after, an open pyometra was confirmed. Later in November 2019, the patient died and necropsy confirmed the presence of two uterine masses; one was located at the cervico-uterine junction and another in the uterine body, with pyometra, and cystic endometrial hyerplasia. Based on histological, special stains, and immunohistochemical examination, it was shown that one of the masses was composed of large, ovoid and polyhedral neoplastic mesenchymal cells with eosinophilic cytoplasm and a few binucleated cells surrounded by collagen fibres. It was tested positive for SMA and vimentin, while negative for desmin, cytokeratin AE1/AE3, EMA, CD34, and S100. The other mass was composed of mesenchymal cells undergoing myxoid degeneration as evidenced by the presence of glycosaminoglycan-rich matrix. It was tested positive for SMA, vimentin, partially positive for desmin, and negative for the other markers. With the aid of human medical nomenclature, these masses were diagnosed as epithelioid leiomyoma and myxoid leiomyoma, respectively. This report provides a clinical presentation, and histologic descriptions of the two variants of leiomyomas that have not been reported in veterinary medicine.
Magnetic Resonance-guided focused Ultrasound Surgery (MRgFUS) is gaining popularity as an alternative to medical and surgical interventions in the management of symptomatic uterine fibroids. Studies have shown that it is an effective non-invasive treatment with minimal associated risks as compared to myomectomy and hysterectomy. MRgFUS can be offered to a majority of patients suffering from symptomatic uterine fibroids. It has been suggested that the use of broader inclusion criteria as well as the mitigation techniques makes it possible to offer MRgFUS to a much larger subset of patients than previously believed. This paper will describe how MRgFUS treatment for uterine fibroids is performed at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia.
A 32-year-old, gravida 2 para 0+1, was managed in Selayang Hospital, Selangor for uterine fibroids in pregnancy and placenta previa major. The lady went into preterm labour at 33 weeks, requiring emergency Caesarean section. Intraoperatively, we found a thinned-out bulge between the intramural uterine fibroids at the posterior uterine wall, which then perforated and was repaired. Persistent bleeding post operatively led to relaparotomy and hysterectomy. Histology of the uterus reported arteriovenous malformation (AVM). We postulate the possibility of these lesions coexisting with uterine fibroids. Screening for uterine AVMs in patients with fibroids may lead to early detection with option of embolization; deferring the need for hysterectomy.
Two cases of leiomyomas of the jejunum presenting with gastrointestinal bleeding of uncertain origin are described. Diagnosis was finally established by selective angiography. Laparotomy and resection of the tumour were successfully performed. The approach and management of this rare tumour are outlined.
Sixty cases with uterine leiomyomata in pregnancy are presented. The incidence was 1 in 1033 deliveries. The median age of the patients was 33.4 years. The majority were primigravidae (60%). A significant number of patients gave a history of infertility (43%) and spontaneous abortions (25%). The commonest antenatal complication was malpresentation and in all these patients the myomata were larger than 6 cm. Typical features of red degeneration occurred in 10% of cases. The cesarean section rate was 73%, the commonest indication being obstructed labor. Severe hemorrhage was encountered at cesarean section in 10 patients, 3 of whom needed hysterectomy. There were no perinatal deaths.
Three sisters who developed recurrent uterine myomata from a very young age are presented. Despite repeated attempts at myomectomy, all three cases had hysterectomies ultimately. Complications encountered during surgery were severe hemorrhage, inadvertent injury to bladder and bowel in two patients and a rare complication of colonic-uteric-cutaneous fistula occurring post-operatively in one patient. Histology of the final hysterectomy specimens in two cases showed low grade leiomyosarcoma and cellular myoma, respectively.
Leiomyomas are benign soft tissue swellings of smooth muscle origin, most commonly found in the uterus. Extra uterine leiomyomas presenting as an abdominal mass is often a diagnostic challenge as such occurrence is rare. We present a rare case of primary abdominal wall leiomyoma, and highlight the importance of laparoscopic approach in the diagnosis and treatment of such tumour.
Myomectomy is rarely performed in pregnancy due to risk of miscarriage or pregnancy loss, bleeding and possible
hysterectomy. Myomectomy is mainly reserved for unavoidable indications such as rapidly growing fibroid or severe
pain with possiblity of red degeneration for which medical treatment failed. However, good outcome had been
reported in selective second trimester myomectomies.
Lingual hamartoma is a rare finding of congenital midline posterior tongue mass. The lesion may be seen as a single anomaly or maybe associated with syndrome especially the Oral Facial Digital Syndrome (OFDS). Here, we report an otherwise normal and healthy two-month-old boy with a congenital midline base of tongue mass presented with snoring and episodic vomiting since the age of 1 month. Tumour excision from the area of foramen of caecum recovered a pinkish pedunculated tumour. Histopathology examination confirmed the diagnosis of leiomyomatous lingual hamartoma. Differential diagnosis, especially for midline tongue mass and other paediatric tongue lesions are discussed. We also discuss the epidemiology, histopathologic features, treatment and prognosis of lingual hamartoma based on the literature review.
A 35 year-old para 1+0 underwent MRgFUS per study protocol for multiple uterine fibroids, the largest of which measured 5 cm. She conceived 10 months following the procedure. The patient was induced at 41+6 weeks and underwent a normal vaginal delivery.
Oral leiomyomas are rare benign tumour of smooth muscle. The first case of oral leiomyoma was reported by Blanc in 1884 and since then more cases has been published following advancement in immunohistochemical study. This tumour has an excellent prognosis and recurrences are extremely rare. We report a case of a recurrent glossal leiomyoma in a patient with HIV infection and the lesion recurred one year after the first excision.
Leiomyomas are the most common benign tumour of the uterus, occurring in 20-40% of women in reproductive age.Most of the myomas arise in the uterus, however extrauterine sites include fallopian tubes, cervix, round ligament, ovary and urethra. A single or polypoidal mass in the vagina is usually a leiomyomatous polyp arising from the cervix or from the cavity of the uterus. Leiomyoma developing de novo from the fibromuscular elements of the vagina is a rare entity. When such a tumour arises from anterior wall of the vagina it is often mistaken for a cervical fibroid. Parasitic leiomyoma is the rarest type of leiomyoma and develop when a leiomyoma attaches itself to another organ. Vaginal leiomyomas usually arise from anterior vaginal wall. We report a case of parasitic leiomyoma in the vagina together with uterine leiomyoma in a 48 year old lady presented with palpable mass perabdomen and anaemic symptoms. The size and location of the tumours necessitated abdominal and vaginal approach for better surgical access.
Pyomyoma (suppurative leiomyoma) is a rare complication of uterine leiomyoma. It results from infarction and infection of a leiomyoma. It may lead to diagnostic and therapeutic difficulties with potential complications such as bacteraemia, uterine rupture, compressive effect to adjacent structures and even death. We report a case of pyomyoma based on the Ultrasound (US) and Computed Tomography (CT) findings and literature review on the subject.
Leiomyoma of the caecum is a rare tumour. While leiomyomata are known to arise from any part of the large bowel, caecum is a rare site. The largest series to date is that of Mackenzie" who reviewed 37 cases of myomatous tumours of the colon, two of which were complicated by perforation. More recently, Swerdlow" reported another case of a perforated caecal leiomyoma. We now report a patient who was operated at the stage of abscess formation without perforation.
Spontaneous rupture of uterine fibroid is rarely encountered. We present a case of a 31-year-old who presented with acute abdominal pain at 9 weeks postpartum. On examination, the abdomen had diffuse tenderness, with rebound tenderness in the suprapubic area and in both iliac fossae. On ultrasonography, a 12.7 × 8.6 × 8.9-cm sized hyperechoic mass was visible on the posterior wall of the uterus. A large amount of fluid was visible in the paracolic gutters and the Pouch of Douglas (POD). The patient underwent an exploratory laparotomy. A ruptured, cystic degenerated uterine fibroid with active bleeding was found, as well as approximately half a liter of free, bloodstained peritoneal fluid and pus. Myomectomy was performed, followed by evacuation of the fluid and clots. The patient's postoperative course was uneventful. In conclusion, preoperative diagnosis of a perforated, uterine fibroid with spontaneous intra-abdominal hemorrhage is difficult; exploratory laparotomy is both diagnostic and therapeutic in this rare, life-threatening condition.
Leiomyoma is a smooth muscle tumour that can arise in any part of the body especially the uterus. Even though it is traditionally linked with hormonal influence, it can also develop in extrauterine organs with a slight female predominance. It is indistinguishable with gastrointestinal stromal tumour (GIST) histologically. We report a case of a 30-year-old gentleman who presented with a huge painful mass in the right iliac fossa. Computed tomography revealed a 10 × 10 cm homogeneous mass arising from the terminal ileum; he subsequently underwent an open right hemicolectomy. Histology showed a well-circumscribed lesion composed of interlacing bundles of smooth muscle fibres of the submucosa with positive smooth muscle actin and H-Caldesmon stains but negative for DOG-1 and CD117 (c-kit) stains which were consistent with leiomyoma. Despite its rarity, this hormone-related tumour needs to be considered regardless of gender. Immunohistochemistry is paramount as it is histologically identical to GIST.
