RESUMO
The central granular cell odontogenic tumor (CGCOT) is a rare benign odontogenic neoplasm composed of varying amounts of large eosinophilic granular cells and apparently inactive odontogenic epithelium. It tends to occur as a small asymptomatic swelling in the posterior region of the mandible with nonaggressive appearance. We report an unusual case of CGCOT in the maxillary region with clinical features of malignancy. The patient underwent surgical treatment, and the 2-year follow-up revealed no signs of recurrence. Central granular cell odontogenic tumor is a very rare condition with few cases reported, especially in the maxillary region. This case highlights the possibility of aggressive behavior by these lesions.

Hamartoma is a proliferation of normal tissues that are considered endogenous to the site of occurrence. In the head and neck region, hamartomas composed of other tissues different from blood and lymphatic vessels (hemangiomas and lymphangiomas) are very uncommon. We report an unusual case of upper lip angiomyolipomatous hamartoma in an 8-month-old patient. The patient underwent surgical treatment and the 1-year follow-up revealed no signs of recurrence. Angiomyolipomatous hamartoma is a very rare condition in the paediatric population group, especially in the head and neck region. It should be considered in the differential diagnosis of congenital lesions in childhood.

Neurofibroma is a benign peripheral nerve sheath tumor that can be occasionally found in the head and neck region as multiple lesions associated with neurofibromatosis type 1 (NF-1) or as a solitary tumor. The real frequency of isolated neurofibromas not associated with NF is uncertain, and lesions in the temporal region are extremely rare. The aim of the current article was to report an unusual case of solitary neurofibroma localized in the temporal and infratemporal regions with 10 years of evolution in a female patient without any other manifestation or familiar history of NF-1. The patient underwent surgical treatment for complete excision of the lesion, and the 2-year follow-up revealed no signs of recurrence.
