Entamoeba histolytica has been rarely reported as superadded infection over carcinomatous growth on rectal brushings. We present a case of 68-year-old male who presented with abdominal pain and bleeding per rectum who was found to have an ulceroproliferative growth on sigmoidoscopy. Rectal brushings revealed coexistence of E. histolytica with malignant cells of adenocarcinoma. No organism was detected on biopsy of the tumor, which also showed adenocarcinoma, because of possible surface colonization of the tumor by Entamoeba ...

Well-differentiated papillary mesothelioma is a rare tumor occurring predominantly in the peritoneum of young women, a few with history of asbestos exposure. A 28-year-old woman presented with ascites and pain abdomen. Ultrasonography and computed tomography scan of the abdomen revealed a mass in the retroperitoneum measuring 15 cm × 12 cm. Histopathological examination along with immunohistochemistry (IHC) confirmed it to be a papillary mesothelioma in the peritoneum. It is difficult to differentiate from more common malignant mesothelioma and papillary adenocarcinoma, which also have poorer prognosis...

Aggressive angiomyxoma (AAM) is an uncommon mesenchymal tumor that predominantly involves the pelvis and perineum of young females. It is often clinically mistaken for more common superficial lesions such as vaginal cysts, labial cysts, and lipomas. A review of the medical literature reveals very few cases of AAM reported in pregnancy. We describe a rare case of AAM in pregnancy, clinically misdiagnosed as prolapsed cervical fibroid.

Cutaneous and intraoral metastasis from any malignancy is not common. Cutaneous spread is usually noted in 5%-10% of high-grade malignancies, as in carcinoma breast, lung, colon, ovary, and malignant melanoma. Only 4.6% cases of cutaneous spread are from renal cell carcinoma (RCC). Intraoral spread from RCC is much rarer with an incidence of approximately 1% of all malignant oral tumors, noted sometimes in tongue, palate, buccal mucosa, gingiva, and lips. RCC is a highly aggressive tumor which requires early diagnosis for increasing the chance of cure...
