Effectiveness of surgical decompression in the treatment of a calcifying cystic odontogenic tumor

The calcifying odontogenic cystic tumor (CCOT) is a benign lesion of odontogenic origin characterized by an ameloblastoma-like epithelium with ghost cells that may calcify. Despite broadly considered as a cyst, some investigators prefer to classify it as a neoplasm. Clinically, it occurs predominantly during the third decade of life. No difference in gender prevalence has been observed nor predilection of the lesion between maxilla and mandible. The most affected region extends from the incisor tooth to bicuspids. The classic treatment of the lesion is full excision, although a different approach may be determined by the possible association with another odontogenic tumor. Depending on the tumor size and the vicinity with important structures, decompression may be undertaken before its complete removal. The present report describes a case of CCOT with large proportions, located at the right maxilla and extending to the maxillary sinus, nasal cavity, and orbital floor. The treatment option was surgical decompression as the initial procedure, with satisfactory outcome. After partial remission, the lesion was fully removed, and the post-operative follow-up was uneventful

Nodular lymphocyte predominance Hodgkin lymphoma of the parotid gland: a case report

The parotid is the most frequent site of primary salivary gland tumors.Lymphomas represent 0.2 to 0.8% of all malignant parotid tumors. PrimaryHodgkin lymphoma of the parotid gland is rare with few cases reported inliterature. The nodular lymphocyte predominance Hodgkin lymphoma (HL)is considered a particular clinical and histopathological subtype of HL. Ithas never been reported in the parotid gland since its incorporation in the2001 World Health Organization Classification. The authors describe a caseof a 32-year-old male who sought medical attention because of a one-yearhistory of right cheek enlargement. A parotid nodule was submitted to a fineneedle aspiration biopsy which disclosed a suspected lymphoproliferativedisorder. A surgical dissection of the parotid gland was performed and anenlarged intraparotid lymph node measuring 4cm in its longest axis wasexcised, preserving the parotid gland integrity as well as the facial nerve.The pathological examination disclosed the diagnosis of nodular lymphocytepredominance Hodgkin lymphoma in this lymph node within the parotid gland.The treatment was completed with local radiotherapy and the 5-year follow upwas uneventful
