Primary peritoneal carcinoma (PPC) is a rare tumor that is histologically and immunohistochemically indistinguishable from epithelial ovarian carcinoma. The diagnosis is usually made after excluding gross ovarian involvement or the ovarian involvement is only confined to the surface. A 68-year-old lady presented with right iliac fossa pain and increasing CA125. The CT scan showed bilateral pelvic adnexal masses with peritoneal deposits within the right side of abdomen. She was initially diagnosed as carcinomatosis peritonei from the omental cake removed after exploratory surgery. She was managed as advanced ovarian tumor with peritoneal metastasis and was then administered six cycles of chemotherapy. Surgical intervention included debulking surgery consisting of total abdominal hysterectomy, bilateral salpingooophorectomy and omentectomy and also with right hemicolectomy. The histopathological findings were of primary peritoneal serous carcinoma with only minimal involvement of the serosal surface of the right ovarian capsule. No microscopic invasion into underlying ovarian cortex and stroma was observed. Multiple tumor deposits were also seen over the right paratubal and paraovarian tissue, both parametrium as well as serosal surface of the terminal ileum and periappendicular tissue. Immunohistochemically, the malignant cells were positive to CA125, focally positive to CK7 and negative to CD20 and Calretinin. PPC is one of important differential diagnosis which needs to be considered in cases of advanced ovarian tumor, although the former can only be ascertained after excluding the ovarian involvement microscopically.

PIK3CA gene mutations in breast carcinoma in Malaysian patients

Somatic mutations of phosphoinositide-3-kinase, catalytic, alpha; PIK3CA gene have been reported in several types of human cancers. The majority of the PIK3CA mutations map to the three "hot spots" - E542 K and E545 K in the helical (exon 9) and H1047R in the kinase (exon 20) domains of the p110alpha. These hot spot mutations lead to a gain of function in PI3 K signaling. We aimed to determine the frequency of PIK3CA mutations in the three most common Malaysian cancers. In this study, we assessed the genetic alterations in the PIK3CA gene in a series of 20 breast carcinomas, 24 colorectal carcinomas, 27 nasopharyngeal carcinomas (NPC), and 5 NPC cell lines. We performed mutation analysis of the PIK3CA gene by genomic polymerase chain reaction (PCR) and followed by DNA direct sequencing in exons 9 and 20. No mutations were detected in any of the 24 colorectal and 27 NPC samples, but one hot spot mutation located at exon 20 was found in a NPC cell line, SUNE1. Interestingly, PIK3CA somatic mutations were present in 6/20 (30%) breast carcinomas. Two of the six mutations, H1047R, have been reported previously as a hot spot mutation. Only one out of three hot spot mutations were identified in breast tumor samples. The remaining four mutations were novel. Our data showed that a higher incidence rate of PIK3CA mutations was present in Malaysian breast cancers as compared to colorectal and nasopharyngeal tumor tissues. Our findings also indicate that PIK3CA mutations play a pivotal role in activation of the PI3 K signaling pathway in breast cancer, and specific inhibitors of PIK3CA could be useful for breast cancer treatment in Malaysia.

Hemangiopericytoma is a very rare angiogenic tumor. In the nasal cavity, it can be considered malignant. It occurs in various parts of the body but those in the nasal cavity account for only 5% of total cases. Less than 200 cases have been reported worldwide involving the nose and paranasal sinuses. Due to its rarity a proper line of management has not been established to tackle this tumour. This article highlights two cases of hemangiopericytoma (HPC), one in an adult and the other in a child, presenting as an intranasal mass.

Karsinoma tiroid biasanya didiagnoskan berdasarkan kriteria morfologi tertentu. Dalam sesetengah kes, diagnosis yang tepat mungkin sukar apabila ciri-ciri morfologi adalah tidak ketara. Kajian ini menilai kegunaan Hector Battifora Mesothelial-1 (HBME-1) sebagai penanda immunohistokimia untuk membezakan tisu tiroid barah dengan bukan barah dan untuk membandingkan ekspresi HBME-1 dalam pelbagai jenis tisu tiroid. Sensitiviti dan spesifisiti HBME-1 sebagai penanda khusus untuk karsinoma tiroid juga dikaji. Sejumlah 54 kes barah dan 54 kes bukan barah tiroid yang didiagnos di Pusat Perubatan Universiti Kebangsaan Malaysia untuk tempoh tujuh tahun telah dikumpul. Semua kes diwarnai dengan HBME-1 dan dinilai oleh tiga pemerhati bebas. Kes-kes tersebut diberi skor berdasarkan nisbah pewarnaan dan dinilai sebagai skor 0 (kurang daripada 10%), 1+ (10-25%), 2+ (26-50%) atau 3+ (lebih daripada 50%). Di samping itu, perkaitan antara skor bagi kes barah dengan peringkat patologi tumor juga dikaji. HBME-1 menunjukkan ungkapan pewarnaan yang lebih signifikan dalam kes barah berbanding bukan barah (P

PMID: 33361730

INTRODUCTION: Primary gastrointestinal melanomas are mucosal malignancies that arise from melanocytes in the oropharynx, rectum, and anus. Anorectal malignant melanoma (ARMM) are exceedingly rare, accounting for less than 1% of all melanomas, 0.1% of all rectal malignancies and 4% of anal malignancies. Diagnosis is frequently delayed as these lesions are often mistaken for haemorrhoids. Histological evaluation with special immunohistochemical stains is often necessary for definitive diagnosis. Due to the aggressive nature, 61% of patients with ARMM would already have lymph node involvement or distant metastases, by the time of diagnosis. Prognosis is usually poor with 5-year survival rate of <20%. We report a case of metastatic ARMM in an elderly lady who presented with symptoms and signs mimicking a haemorrhoid.

CASE REPORT: A 69-year-old lady presented with one year history of intermittent rectal bleed and an anorectal mass that was initially treated as haemorrhoid. Colonoscopy showed a hyperpigmented mass in the anorectal region which was confirmed as malignant melanoma on histopathological examination. Imaging with CT and MRI demonstrated locally advanced tumour with distant metastases to the liver and lung. Patient was referred for palliative management.

CONCLUSION: ARMM is a rare malignancy and often presented with non-specific clinical signs. Diagnosis is frequently delayed without high index of suspicion. MRI pelvis is the imaging of choice to assess local extent of disease. Histologic evaluation with special immunohistochemical stains is often necessary for definitive diagnosis. Prognosis is poor despite surgical and chemotherapeutic interventions.

Purpose: To evaluate the usefulness of ultrasound guidance in percutaneous needle biopsy for musculoskeletal tumours.
Methods: Forty-five consecutive patients underwent ultrasound-guided needle biopsy. An additional group of 50 patients who underwent needle biopsy without ultrasound guidance was retrospectively selected as historical control. The sample was considered adequate when a diagnosis can be made, and diagnostic when the diagnosis is similar to the final report based on the excised tumour.
Results: Adequacy of the biopsy samples was 84% in ultrasound-guided group as compared 76% in the group with no ultrasound guidance. Diagnostic accuracy was 64% in the ultrasound-guided group and 52% in the group without ultrasound guidance. Both of these differences were not statistically significant.
Conclusions: Ultrasound guidance did not provide a significant advantage in the biopsy of musculoskeletal tumours. Diagnostic accuracy seems to improve with the use of larger 14 gauge biopsy needle but further evaluation is necessary.
