A true collision tumor at the pyloric antrum of the stomach has been rarely described in literature. In this article, we report a gastric collision tumour comprising adenocarcinoma with carcinoid in a 48 year old man. The morphologic, immunohistochemical and electron microscopic findings of this rare case is discussed.

Allergic fungal rhinosinusitis is a unique disorder characterised by specific immunological hypersensitivity to certain fungal antigens usually presenting with nasal polyps and characteristic CT findings. It is a noninvasive disease and on histopathology shows formation of allergic mucin containing numerous eosinophils, charcot leyden crystals and scattered fungal hyphae. Many cases have been reported in western journals but it has been rarely reported in Indian literature. This case is probably the first case in India. It is presented here for its rarity.

Entomopthoromycosis is a rare subcutaneous infection and manifests in two clinically distinct forms. Subcutaneous zygomycosis which manifests as a painless nodule on the trunk or the extremities and rhinofacial zygomycosis which is a locally progressive infection of the nasal cavity, paranasal sinuses and soft tissues of the face. Neither of these two forms occur in patients with underlying disease or defective immunity. Here we report four cases of entomopthoromycosis.
