CARCINOMA COLON SIGNET-RING CELL TYPE: A RARE CASE REPORT

Carcinoma colon ranks third among the commonest cancer in the world, while seen less common in the Asian countries however lately an increasing trend has been observed. Majorly the elderly population is at an increased risk of colon cancer however early onset of the disease has also been observed in past few years. Various histologic subtypes with different prognoses are present, but the most common histological type is Adenocarcinoma (1). Signet-ring cell carcinoma (SRCC) is a known rare subtype of colorectal carcinoma (< 1%) officially recognized by the WHO, mucinous types are aggressive with poor outcomes and are most commonly diagnosed around the fourth to fifth decade of life comprising only 1% of colorectal cancers. So we report a case of a 40-year-old male with adenocarcinoma colon of signet ring cell type. The patient presented with localized abdominal discomfort with only generalized weakness and fatigue which was later evaluated to be a near-obstructing right-sided colonic mass. Patient was taken up for surgery and was found to have diffuse carcinomatosis

AMELANOTIC MELANOMA- RARE CASE REPORT

Amelanotic melanoma is an uncommon type of of melanoma which lacks melanin pigment (1). Of all the melanoma cases, approximately 2- 8% cases represents amelanotic melanoma. The exact prevalence of this malignancy is more due to misdiagnosis. Due to lack of clinical criteria and pigmentation, the condition often detected late (2). Amelanotic melanomas are commonly found on the face, which shows microscopically the characteristics of desmoplasia (desmoplastic melanoma), but other body parts can also be involved (4)

PYLORIC GLAND ADENOMA OF STOMACH: A RARE CASE

Pyloric gland adenoma is an uncommon precancerous polypoidal growth. Pyloric gland adenoma of stomach accounts for 2.7% of all gastric polyp. Mostly Pyloric gland adenoma are found in stomach but can be found in other anatomical sites. Pyloric gland adenoma of stomach occur in elderly population and having female predominance. Pyloric gland adenoma of stomach is commonly seen in chronic gastritis patients, autoimmune gastritis but can also occur in some genetic disease like familial adenomatous polyposis and Lynch syndrome. Early identification and therapeutic polypectomy by endoscopically and histopathological evaluation and confirmation of pyloric gland adenoma may reduce the chances of transformation of invasive adenocarcinoma
