Abstract We describe a case of ovarian adenoid cystic carcinoma (ACC) of the left ovary in a 23-year-old woman. The tumor had the typical cribriform pattern of ACC, lacked any component of surface epithelial carcinoma, and showed myoepithelial differentiation. The features of salivary gland–type tumor seen in this case are unusual and different from those of so-called ACC-like carcinomas of the ovary, which only resemble the salivary gland tumor histologically.

Adenoid cystic carcinoma (ACC) is an aggressive salivary gland tumor that frequently displays perineural invasion and is often associated with translocations or overexpression of the MYB oncogene. Detailed analyses of MYB transcripts from ACC patient samples revealed that ACC tumors utilize an alternative MYB promoter, which is rarely used in normal cells or other tumor types. The alternative promoter transcripts produce N-terminally truncated Myb proteins lacking a highly conserved and phosphorylated domain, which includes the pS11 epitope that is frequently used to detect Myb proteins. In RNA-seq assays, Myb isoforms lacking the N-terminal domain displayed unique transcriptional activities, regulating many genes differently than full-length Myb. Thus, a regulatory pathway unique to ACC activates the alternative MYB promoter, leading to the production of a truncated Myb protein with altered transcriptional activities. This could provide new therapeutic opportunities for ACC patients.

CONTEXT AND OBJECTIVE: Salivary gland tumor management requires long-term follow-up because of tumor indolence and possible late recurrence and distant metastasis. Adenoid cystic carcinoma (ACC) accounts for 10-15% of such tumors. The aim here was to evaluate surgical and clinical management, staging and follow-up of ACC patients in one academic institution. DESIGN AND SETTING: Retrospective study at Head and Neck Service, Universidade Estadual de Campinas. METHODS: Data on 21 patients treated between 1993 and 2003 were reviewed. Management utilized clinical staging, histology and imaging. Major salivary gland tumor extent was routinely assessed by preoperative ultrasonography. Diagnosis, surgery type, margin type (negative/positive), postoperative radiotherapy and recurrence (presence/absence) were evaluated. RESULTS: There were eleven major salivary gland tumors (52.3%), seven submandibular and four parotid. Ten patients (47.7%) had minor salivary gland ACC (all in palate), while the submandibular was the most frequently affected major one. Diagnoses were mostly via fine-needle aspiration (FNA) and incision biopsy. Frozen sections were used for six patients. There was good ultrasound/FNA correlation. Sixteen (76%) had postoperative radiotherapy. One (4.7%) died from ACC and five now have recurrent disease: three (14.2%) locoregional and two (9.5%) distant metastases. CONCLUSION: Adenoid cystic carcinoma has locally aggressive behavior. In 21 cases, of ACC, the facial nerve was preserved in all except in the few with gross tumor involvement. Treatment was defined from physical examination, imaging, staging and histology.

Background: Adenoid cystic carcinoma is a malignant salivary gland tumor located in the head and neck region. Although complete surgical resection and complementary radiotherapy have been shown to improve long-term survival rates, the prognosis of adenoid cystic carcinoma remains poor. Ki-67 expression is considered a marker for the cellular proliferation rate, the detection of its expression usually being related to the aggressiveness and unfavorable prognosis of adenoid cystic carcinoma in the salivary gland. Purpose: This study was conducted to quantify the expression of Ki-67 in adenoid cystic carcinoma and to correlate the result with clinical parameters and histopathological grading in determining the prognosis. Methods: Twenty three cases of salivary gland adenoid cystic carcinoma were identified at the Department of Anatomical Pathology, Dr. Hasan Sadikin Hospital between 2013 and 2015. Clinical data such as age, gender, location of tumor and histopathological grading was also collected. The expression of Ki-67 was assessed by immunohistochemical means to determine the correlation of Ki-67 with clinical parameters and histopathological grading. Results: There were no significant differences between the expression of Ki-67 and clinical parameters, although a very strong correlation existed between the expression of Ki-67 and histopathological grading (p < 0.01). Conclusion: There were no correlation between the expression of Ki-67 and clinical parameters, although a correlation existed between the expression of Ki-67 and histopatological grading in salivary gland adenoid cystic carcinoma. Thus, clinical parameters were unusable in determining the prognosis of adenoid cystic carcinoma, although Ki-67 expression could be used for this purpose.

Salivary gland tumors are a rare tumor entity within malignant tumors of all tissues. The most common are malignant mucoepidermoid carcinoma, adenoid cystic carcinoma, and acinic cell carcinoma. Pleomorphic adenoma is the most recurrent form of benign salivary gland tumor. Due to their low incidence rates and complex histological patterns, they are difficult to diagnose accurately. Malignant tumors of the salivary glands are challenging in terms of differentiation because of their variability in histochemistry and translocations. Therefore, the primary goal of the study was to review the current literature to identify the recent developments in histochemical diagnostics and translocations for differentiating salivary gland tumors.
