Adenoid cystic carcinoma (ACC) of the maxilla is a rare malignancy arising from minor salivary glands. The clinical and radiological appearance may be similar to any odontogenic/nonodontogenic pathology. This study aims to report a rare case of primary central ACC of the anterior maxilla.

Case Report: 

A 31-year-old man was referred to the Department of Oral and Maxillofacial Surgery complaining of swelling and pain in the right anterior maxilla for 3 months. The patient has noticed swelling and pain in this side since about five months before and instead of diagnosing this tumoral lesion, false diagnosis and unsuccessful root canal therapy were considered. A biopsy was performed in the central region and microscopically, the lesion showed tumor cells arranged in sheets in fibrous stroma islands of epithelial cells showing a classical “Swiss cheese” pattern. Based on clinical, radiographic, and CBCT evaluation and positive immunohistochemistry of CD63, and C-Kit confirmed ACC diagnosis. After the diagnosis, the lesion was completely removed by enucleation and curettage performed by the surgeon. Postoperative radiotherapy was performed. Follow-up within 3 years since the initial diagnosis showed no sign of recurrence.

Based on the results of this study, early diagnosis and treatment of ACC can lead to successful treatment and patient survival.

Incidence of skin malignancy is increasing recently and includes 11% of all human malignancies. Basal cell carcinoma (BCC) is a primary malignant epithelial with slow expansion and invasive status. Squamous cell carcinomas (SCC) constitutes about 20% of all skin tumors is originated from surface epithelial dysplasia. This study aim to report a case of SCC of the scalp in a patient with history of BCC with frequent relapses.
CASE REPORT: The patient is a 75-year old man with a history of diabetes for 15 years, smoking and alcohol use for a long time, who suffered from BCC in the last 20 years and underwent surgery twice due to relapse of the lesion. Since last year, 2-3 cm injuries and endophytic appearance with mired center and prominent and irregular margins near leukoplakia areas were created in the same BCC spot. The results of histopathology confirmed Squamous cell carcinoma.
Since a high percentage of patients with a history of non-melanoma tumor will suffer from other non-melanoma tumors in the next 5 years, timely diagnosis, appropriate treatment and regular follow-up can reduce the chance of disability, metastasis and death significantly. Therefore, informing these patients for appropriate treatment and follow-up to prevent relapse can help to increase their life span.
