RESUMEN
Isolated caudate lobe excision is an uncommon procedure. We report a 41-year-old lady who underwent isolated caudate lobe excision for a solitary metastatic lesion from a previously operated adenocarcinoma of rectum. This is the first such reported case from India.

Microcystic adenoma or serous cystadenoma is an uncommon tumor and accounts for 1-2% of the exocrine neoplasms of the pancreas. Usually unifocal, they present as single, large, well-demarcated multiloculated cystic tumors, ranging in size from 1 to 25 cm. Multifocal variants or diffuse serous cystadenomas are extremely rare. We present 2 cases of which 1 is a diffuse variant affecting the body, tail and part of the neck of the pancreas. In both the patients the tumors were detected incidentally. We highlight on the diffuse variant in view of its rarity and present a review of literature. In this case the entire body and tail of the pancreas was spongy replaced by multicystic lobules and hyalinized fibrocollagenous stroma. The cysts were lined by low cuboidal glycogen containing bland cells. Such a unique presentation wherein the entire body and tail of the pancreas is replaced with multiple cysts is a diffuse presentation of microcystic adenoma and a search through literature revealed only 7 such cases among the 15 cases with multifocal presentation reported.

Pancreatic endocrine tumors (PETs) are unusual tumors arising from cells belonging generically to the amine precursor uptake and decarboxylation systems. We present a case of a calcitonin-secreting PET in a 56-year-old female who presented with watery diarrhea, dehydration and hypokalemia. Investigation revealed hypercalcemia, hyperphosphatemia, hypercalcitonemia and a well-defined mass in the head of the pancreas on CT scan. Following a pancreaticoduodenectomy her serum calcitonin levels returned to normal and diarrhea disappeared. The identification of this particularly rare presentation of a calcitonin-secreting PET provides the opportunity to examine this pathological entity within the context of the very few previously reported instances of this disease.
