Amelanotic melanoma masquerading as a superficial small round cell tumor: a diagnostic challenge.

Malignant melanoma poses a remarkable capacity for morphological diversity and often presents as a diagnostic challenge due to its wide clinical presentation. We present a case of a 73-year-old lady, with a large superficial ulcerative nodular mass on the flexor aspect of the right upper arm. On fine needle aspiration poorly differentiated round cell tumor was suggested, with histopathology also supporting the same diagnosis.

Isolated primary renal echinococcosis: a rare entity.

Primary renal echinococcosis, a rare entity in diseases involving the kidney, accounts for 2-3 % of all cases. We present a case of 37-year-old female presenting with pain in the right iliac fossa. Radiologically, both ultrasound abdomen and CECT diagnosed as hydatid cyst, mild to moderate hydronephrosis, proximal hydroureterosis, and a possibility of rupturing into the pelvicalyceal system.
