[Heterotopic brain tissue in the pharynx].

The presence of heterotopic brain tissue in the head and neck region is exceptional. Most reported cases have been observed in the nasal region and are called nasal gliomas. The case of a 10-month-old boy with heterotopic brain tissue on the soft palate and nasopharynx is reported. Surgical treatment was successful and no complications or recurrences have been observed in 7 years of follow-up. The main pathogenic theories and nomenclature are analyzed.

[Naso-alveolar cysts. A report of 10 new cases and a review of the literature].

Nasoalveolar cysts, also known as Klestadt's or nasolabial cysts, are uncommon midfacial lesions. Ten cases treated at the 12 de Octubre University Hospital are reported, describing the most relevant clinical and pathological findings are reported. The main theories of the origin of these developmental, non-odontogenic cysts are discussed. A review of the literature is included.

[Eosinophilic cholecystitis: an infrequent cause of cholecystectomy].

Eosinophilic cholecystitis is a rare form of cholecystitis. Histologically, it is characterized by a dense, transmural leukocyte infiltrate composed of more than 90% eosinophils. The etiology remains obscure, although it had been associated with allergies, parasites, hypereosinophilic syndromes, eosinophilic gastroenteritis, cholelithiasis, and acalculous cholecystitis. Here we report an eosinophilic cholecystitis gallstone-associated case, the only one with this histopathologic diagnosis among 5,537 cholecystectomies made in our hospital in the last years.

[Primary nasal sinus malignant melanomas].

Primary malignant melanoma of the mucosa of the nasal and paranasal sinuses is rare, difficult to treat, and usually has a poor prognosis. Seven cases, six women and one man (mean age 76.5 years), were treated at the Hospital 12 de Octubre (Madrid, Spain) during the period 1982-1994. The presenting symptoms, diagnostic evaluation, morphology, therapeutic modalities, histological evaluation, and clinical course were reviewed. Three patients were treated surgically and three received palliative irradiation. All had local recurrence or distant metasfases within 15 months after concluding treatment. The seventh patient refused treatment.

[Branchial cysts with heterotopic salivary tissue in the upper third of the neck].

The presence of heterotopic salivary gland tissue (HSGT) in rather uncommon in the neck. Usually it has been located in its lower third. HSGT in the upper neck is believed to be a rare entity. Two cases of HSGT in the upper neck are presented, with a review of their clinical and histopathological characteristics. The embryologic derivation of salivary tissue and close association with the branchial apparatus are discussed. The possibility of neoplastic transformation must always be considered in these uncommon lesions.
