Basal cell adenocarcinoma of the maxillary sinus: A case report

Abstract Background: A basal cell adenocarcinoma (BCAC) is a low-grade malignancy of the salivary glands. A BCAC of the minor salivary gland is a rare disease, which is extremely rare in the maxillary sinus without invading from the palate and buccal mucosa. The histopathological characteristics of a BCAC are similar to those of a basal cell adenoma (BCA). However, BCAC can be differentiated from BCA based on its tendency to invade surrounding tissues. Surgical resection is the first-line treatment for BCACs. We report a case of a BCAC arising from the maxillary sinus minor salivary glands in an 82-year-old man.Case presentation: In 2016, the patient presented with recurrent epistaxis, and he was referred to our department because a tumor was found in his left nasal cavity. Gross resection using the Denker operation was performed. Histopathological examination revealed no surrounding tissue invasion; therefore, BCA was diagnosed. In 2017, the recurrent lesion was resected using endoscopy as much as possible, and the histopathologic findings again revealed a BCA.In 2019, he developed diplopia, frequent epistaxis, and buccal swelling. The recurrence of maxillary sinus tumor was shown again with invasion of surrounding tissues, and we presumed a clinical diagnosis of a left maxillary carcinoma (suspected BCAC). When we performed partial maxillary resection by the Weber–Ferguson incision, we found that the tumor had partially invaded the bone of the orbital floor; thus, the floor of the orbit and orbital fat were partially resected. Finally, the tumor was diagnosed as a BCAC. Conclusion: We report a BCAC arising from the maxillary sinus. This is an extremely rare sinus tumor, and differentiation of BCAC and BCA is important from a clinical or histopathological examination. A partial maxillectomy with a Weber–Ferguson incision was required for complete resection. When a malignancy is suspected in the recurrent maxillary sinus tumor, it is important to have a wider surgical field than that of the previous surgery to ensure complete resection.

Basal cell adenocarcinoma is a low-grade malignancy of the salivary glands. Basal cell adenocarcinoma of the minor salivary gland is an extremely rare disease that originates from the maxillary sinus. The histopathological characteristics of basal cell adenocarcinomas are similar to those of basal cell adenomas. However, basal cell adenocarcinomas can be differentiated from basal cell adenomas based on their tendency to invade surrounding tissues. Surgical resection is the first-line treatment for basal cell adenocarcinomas. An 86-year-old man underwent operations for a maxillary sinus tumor twice in our department. The pathological results of the tumor at both times revealed basal cell adenoma. After 4 and 5 years since the last operation, the tumor recurred, and the patient was treated with partial maxillectomy using Weber–Ferguson incision. We observed invasions to the surrounding tissue, and based on immunohistochemical findings, the patient was diagnosed with basal cell adenocarcinoma. Herein, we present an extremely rare case of basal cell adenocarcinoma arising from the maxillary sinus, in detail.

Salivary Gland Tumours

Abstract Basal cell adenocarcinoma is an unusual basaloid tumour that usually affects the parotid and very rarely involves the submandibular or minor salivary glands. It constitutes 1.6% of all salivary gland tumours and occurs as an asymptomatic freely mobile mass with occasional lymph node metastasis. Differentiation from benign salivary gland tumours like basal cell adenoma is accomplished by determining the depth of tumour invasion and patterns of growth or infiltration. Although it is categorised as a low-grade malignancy, it has a high propensity for recurrence. Surgical excision with a wide margin is the preferred course of treatment with radiotherapy being reserved only for tumours of the minor salivary glands with a diffuse pattern of infiltration. We present here a case of basal cell adenocarcinoma with a rare presentation in the minor salivary glands of the tongue which arose from a previously treated basal cell adenoma in the same site.

First Case

Basal cell adenocarcinoma (BCAC) is a rare neoplasm accounting for only 2.9% of all salivary gland neoplasms. BCAC involving palatal minor salivary glands are exceedingly rare, and only 10 cases have been reported in the literature. The treatment of choice is surgical excision. Here, we report a case of a 55-year-old male patient with massive BCAC of palatal minor salivary gland extending into the maxillary sinus. This is the first case of BCAC treated by radiotherapy followed by chemotherapy. A follow-up check conducted after 14-months showed good prognosis.

Complete Surgical Excision

Mucinous cystadenocarcinoma of minor salivary glands is an extremely rare entity that has only recently been described, with a few published cases in the English literature. A 42-year-old woman with a history of a surgically excised mucinous cystadenoma of the oral tongue, presented with a painful swelling in the oral tongue slowly growing for 1 month. On clinical examination, there was a firm, relatively well-circumscribed mass in the left posterior border of the mobile tongue. Subsequent MRI scan revealed a heterogeneous lesion composed of multiple cysts separated by contrast enhancing septa, in the posterior two-thirds of the left tongue. Imaging findings were similar to those of the previously resected mass, suggesting local relapse of the primary lesion. A complete surgical excision was performed and the histopathological examination revealed typical features of a low-grade mucinous cystadenocarcinoma of minor salivary glands.
