RESUMEN
Primary thyroid lymphomas (PTLs) are rare neoplasms which in the past have been classified by various schemes. Clinicopathological findings of two cases which were diagnosed in the past one year in our institute are presented using the Revised European and American classification (REAL) for lymphomas. Both cases presented as enlarging neck masses in elderly female patients, in association with lymphocytic thyroiditis. One case was diagnosed as a MALT (mucosa associated lymphoid tissue) lymphoma while the other was a diffuse large cell lymphoma (DLCL).

A variety of salivary gland tumours histologically show the presence of clear cells. Clear cell adenocarcinoma of salivary glands (CCASG) is a distinct clinico-pathologic entity arising in the minor salivary glands of mainly the oral cavity in elderly women and having a low grade malignant potential. A case occurring in the maxillary sinus and extending to the nasal cavity is reported.

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.
