Glomangiopericytoma of nasal cavity.

Glomangiopericytoma/sinonasal type hemangiopericytoma is a rare sinonasal neoplasm arising from the pericytes surrounding capillaries and accounts for less than 0.5% of all sinonasal tumors. This tumor differs from conventional soft tissue hemangiopericytoma in location, biologic behaviour and histologic features. Glomangiopericytoma is a borderline low malignancy tumor with a good prognosis after complete surgical resection. We report a case of 60-year-old woman who presented with progressive nasal obstruction and frequent nasal bleeding and was diagnosed as glomangiopericytoma on histopathological and immunohistochemistry findings. Histological characteristics, differential diagnosis and prognosis of this tumor are discussed in this article. This case has been reported because of its rarity and an array of differential diagnosis.

Androgen - secreting steroid cell tumor of the ovary.

Steroid cell tumors (SCTs), not otherwise specifi ed of the ovary are rare subgroup of sex cord tumors, which account for less than 0.1% of all ovarian tumors and also that will present at any age. The majority of these tumors produce steroids with testosterone being the most common. A case of a 28-year-old woman who presented with symptoms of virilization is reported. Although SCTs are generally benign, there is a risk for malignant transformation. Surgery is the most important and hallmark treatment.

Recurrent Hypoglycaemia in Organophosphorus Compound Poisoning - An Unusual Complication.

Organophosphorus compound poisoning commonly presents with muscarinic, nicotinic and central nervous system manifestations. Endocrinal complications of various organophosphorus compounds are rare and cannot be explained by commonly known mechanisms. We report a clinically proven case of organophosphorus compound poisoning in a young male, in whom at least 22 episodes of hypoglycaemia (blood sugar levels in the range of 47–80 mg %) were observed over 2 weeks during his hospi-talization. Hypoglycaemic episodes completely disappeared upon recovery from poisoning. The exact mechanism for such recurrent hypoglycaemia requires detailed evaluation. This report emphasizes the need to observe blood sugar levels in patients with organophosphorus compound poisoning, so as to detect and promptly treat this rare yet important and correctable complication.
