ABSTRACT
Urinary bladder neoplasm is the 10 most common cancer in the world, predominantly affecting males. Nowadays incidence of urinary bladder carcinoma in female has increased. It is a uncommon type carcinoma of urinary bladder. It resembles to non-keratinizing carcinoma of nasopharynx. This study report a case of 65 years old male presented with painless gross hematuria for 3 weeks. Patient was a known case of Meckel's diverticulum. Ultrasonography and cystoscopy showed a mass on lateral wall of urinary bladder measuring 3x3 cm . A radical cystectomy of the urinary bladder tumor was done. He was diagnosed as case of lymphoepithelioma like carcinoma of urinary bladder along with benign prostate hyperplasia and Meckel's diverticulum was made with stage 2. According to the WHO classification criteria, Lymphoepithelioma like carcinoma is a subtype of undifferentiated carcinomas. Immunohistochemical stains are helpful to differentiate Lymphoepithelioma from primary lymphoma of the bladder. Differentiation of LELCB from urothelial carcinoma is important, since it has better prognosis compared to pure urothelial carcinoma. It is important to diagnose this neoplasm for therapeutic as well as prognostic purpose.
ABSTRACT
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)
ABSTRACT
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
