Basal cell adenoma is a rare type of benign salivary gland tumor found most commonly in the parotid gland. We present a rare case of basal cell adenoma arising in the minor salivary gland of the upper lip. The patient was a 59-year-old Japanese man who visited our department in December 2012 with a chief complaint of a mass in the upper lip, which had increased in size over several years. A mobile, elastic, and relatively soft mass without tenderness was palpable in the upper lip region. The mucosa of the upper lip covering the mass was normal. Tumor extirpation was performed under local anesthesia. Histologically, the tumor had a capsule and was composed of islands of relatively uniform, monotonous cells. Immunohistochemically, the inner tumor comprised tubuloductal structures that showed strong staining for CK7, while the outer tumor showed weak staining for CK7. The outer tumor cells also stained positively for CD10 and p63. The MIB-1 (Ki-67) labeling index was extremely low. Basal cell adenoma was diagnosed based on these results. The postoperative course was uneventful 12 months after surgery and there has been no recurrence.

ABSTRACTBasal cell adenoma is an uncommon benign salivary gland neoplasm, presenting isomorphic basaloid cells witha prominent basal cell layer. Taking into account that basal cell adenomas represent 1% of all salivary gland tumors, being the majority of cases in the parotid glands, the goal of this paper is to report a case of basalcell adenoma of the upper lip arising from minor salivary gland.

Abstract The seromucinous glands of the bronchi can give rise to tumors resembling those of the salivary glands. Basal cell adenoma (BCA) has not been reported in salivary gland-type tumors of the lung. Here, we report a case of an 86-year-old Asian man who suffered from pneumonia in the left upper lung field that may be associated with an endobronchial tumor occluding B1 + 2a + b. The bronchoscopic biopsy of the tumor revealed that the basaloid cells, which constituted a major component of the tumor and were positive for p40/p63 immunohistochemistry, exhibited a cord-like structure. The Ki-67 (MKI67) staining was less than 1% positive. These findings suggest that the endobronchial tumor was BCA of the lung, which caused obstructive pneumonia in the patient.

Background. The presence of two or more tumor entities growing in adjacent locations within the salivary gland is very rare, and pathologic studies on such lesions are limited, particularly those with molecular information. Since the clinical history and imaging studies are usually nonspecific, accurate diagnosis and clinical management largely depend on a thorough histological examination. Methods and Results. We describe a 71-year-old man with an unusual case of hybrid salivary gland tumor composed of mucoepidermoid carcinoma and basal cell adenoma. Molecular analysis revealed differing driver genetic alterations in each component. Conclusions. Hybrid salivary gland tumors are rare, and their pathogenesis is controversial. The combination of mucoepidermoid carcinoma and basal cell adenoma has not been previously described. While malignant transformation of adenoma to carcinoma seems plausible, gene sequencing was more suggestive of their independent derivation. Key to appropriate surgical management is identifying the more aggressive component, ideally at the time of intraoperative consultation.

Basal cell adenoma is a rare benign salivary gland neoplasm. The most common location is in parotid region. Clinically, gradual growth and firm consistency are seen. They account for 1 to 3% among all salivary gland neoplasms. Prominent basaloid cells with cluster of isomorphic cells and interspersed trabeculae are present histopathologically. In this article, we present a rare case of basal cell adenoma of retromolar region from minor salivary gland origin.
