RESUMO
BACKGROUND: Primary ductal adenocarcinomas of the lacrimal gland are very rare. This neoplasm shares some histological and immunohistochemical similarities with salivary duct carcinoma. CASE PRESENTATION: Here, we present a case of a 55-year-old Moroccan man with lacrimal gland adenocarcinoma. He underwent orbital exenteration with lymph nodes dissection and ipsilateral parotidectomy. After surgery, he was lost to follow-up and died 13 months later. CONCLUSIONS: Lacrimal gland tumors are rare but highly aggressive salivary gland tumors. Complete excision with adjuvant radiotherapy is recommended.

Atypical teratoid/rhabdoid tumors are rare and highly malignant central nervous system tumors. They have no specific radiological features and often present several histological components that make a problem in differential diagnosis with medulloblastoma and primitive neuroectodermal tumors. We present the case of a newborn girl complained of a gradual proptosis of the left eye secondary to an expansive lesional process of the optic nerve. The location at the optic nerve, reported only twice in the literature, and an exclusive rhabdoid appearance on biopsy added additional differential diagnosis problems. The proptosis worsened and the infant died few days after two cycles of chemotherapy.
