Omento-mesentral myxoid hamartoma--a case report.

Omento-mesentral myxoid hamartoma, a very rare lesion seen in children, is reported in a three year old child. Its rarity, problem in its clinical pre-operative diagnosis, its characteristic gross and microscopic features, its benign, non recurrent clinical course is stressed.

Granular cell ameloblastoma of jaw. A report of rare case and brief review of literature.

Ameloblastoma is an epithelial odontogenic tumour of the jaw and exhibits diverse microscopic patterns which occurs either singly or in combination with other patterns. The rare granular cell variant is seen in combination usually with follicular or plexiform subtypes. The reported case reveals the microscopic patterns characteristic of granular cell variant only, which is uncommon. The tumour was excised and no recurrence has been observed after nineteen months of surgery.

Immunoglobulin profile in mycetoma.

Serum samples obtained from 25 patients of mycetoma caused by Madurella mycetomi in 18, Streptomyces somaliensis in 5, Streptomyces madurae and streptomyces palletierii from 1 each and also from 25 healthy controls were evaluated for immunoglobulins IgG, IgM and IgA by radial immunodiffusion method using tripartigen plates. All the three classes of immunoglobulins showed increased concentration in cases of mycetoma by M. mycetomi and S. pelletierii. The raised levels of IgG and IgM in cases of mycetoma caused by S. madurae and S. somaliensis where bones were involved, were not statistically significant. IgA was consistently high in all cases of mycetoma irrespective of causative agent and tissue involved. These alterations may possibly reflect relatively poor IgG and IgM response in individuals with extension of mycetoma lesion to bones.

Cerebral chromoblastomicosis--a rare case report of cerebral abscess and brief review of literature--a case report.

A rare case of Cerebral Chromomycosis caused by chromogenic fungus Cladosporium trichoides in a 35 year old male with classical presentation of cerebral abscess is being presented. The case report lays emphasis on the histological diagnosis of chromogenic fungus in the wall of the abscess cavity, surgically removed from a well delineated circumscribed lesion in the frontal lobe of the cerebrum. The causative fungus could be detected even in unstained paraffin sections. The diagnosis could be made only after surgical removal and histopathological examination. The mycological culture could not be made as the material was received in formaldehyde fixative. The unique features of the case is its recurrence free uneventful survival five years after surgical excision. This is probably the fifth reported case of cerebral chromomycosis from India and first of its type from arid zone of Rajasthan.

Cutaneous loxoscelism.

A case of spider bitea presenting as cutaneous loxoscelism is reported. The clinical features and management of spider bite are highlighted and the relevant literature has been reviewed.
