Adenoid cystic carcinoma of the external auditory canal: Report of two cases.

Adenoid cystic carcinoma occurring in the external auditory canal is very rare. Two cases are being reported. One was diagnosed on cytology based on which surgery was planned. In the second case, fine needle aspiration procedure had to be abandoned due to severe pain and a biopsy was required for its diagnosis. Morphologically, it resembles its more common salivary gland counterpart. Though severe pain during needling may be a limiting factor, adenoid cystic carcinoma of external auditory canal can be confidently diagnosed on cytology based on which surgical management can be planned.

Multilocular peritoneal inclusion cyst--a case report.

Multilocular Peritoneal Inclusion Cyst (MPIC) is a rare mesothelial lesion. It is most commonly found in women of reproductive age group involving the abdominal and pelvic peritoneum. Previously, this lesion was often confused with cystic lymphangioma, but now its mesothelial origin has been confirmed. We report a case of a 26-year old female who underwent Caesarean section during which cysts which were multiloculated, thin-walled and filled with serous fluid, were incidentally discovered. Its histopathologic examination established the diagnosis

Pneumatosis cystoides intestinalis: disease or sequel? A case report and review of theories regarding pathogenesis.

Pneumatosis cystoides intestinalis is an uncommon condition characterized by gas filled cysts within the bowel wall. We present a case of a 40-year old male who complained of abdominal pain and distension. The clinical diagnosis was intestinal obstruction and intraoperative impression was intestinal lymphangioma. The resected segment of the bowel showed multiple thin walled, tense, air-filled cysts on the serosal surface, which collapsed with a popping sound when pricked. The histologic diagnosis was pneumatosis cystoides intestinalis. Pneumatosis cystoides intestinalis has varied clinical manifestations, course and outcome depending on its benign or fulminant form. There are varying theories regarding its pathogenesis and it is seen in association with a variety of diseases. Hence it should be interpreted with relevance to its entire clinical context, as it may not be a disease in itself but a sequel to other conditions.
