IgG4-RD is a newly recognized immunomediated fibroinflammatory condition characterized by several features a tendency to form tumefactive lesions at multiple sites, lymphoplasmacytic infiltrate, fibrosis and obliterative phlebitis. Often but not always, the serum IgG4 concentrations are also elevated. Immunohistochemistry for IgG4 is helpful to clinch the diagnosis. Here, we describe a case of 65-year-old male with IgG4-related chronic sclerosing sialadenitis of the s ubmandibular gland. We have discussed the histopathological criteria to diagnose this entity.

We report two cases of rhinoentomophthoromycosis in an 18-year-old female and a farmer of 35 years residents of Chhattisgarh shifted from Madhya Pradesh and Orrisa. It was diagnosed by microscopy and isolation C. coronatus in culture. The patient presented with a swollen nose with obstruction that had progressed slowly over 1 year. His nasal swelling was bilateral, diffuse, mildly tender, erythematous, nonpitting, with mucosal crusting and hypertrophy of inferior turbinates but no regional lymphadenopathy. Culture of tissue from the nasal biopsy on sabouraud dextrose agar yielded multiple colonies o
