“…It is most aggressive type of squamous cell carcinoma affecting the jaw. Revised World Health Organization (WHO-1992) (Waldrum and Mustoe) classification has categorized PIOC broadly into the following types [6].

Type 1: PIOC ex odontogenic cyst

Type 2a: malignant ameloblastoma

Type 2b: ameloblastic carcinoma arising de novo ex ameloblastoma or ex odontogenic cyst

Type 3: PIOC arising de novo

Keratinizing

Nonkeratinizing

Type 4: intraosseous mucoepidermoid carcinoma

Present tumor was found to arise from a surgical extracted site of the jaw.…”

Carcinoma arising primarily from the jaw is a locally aggressive lesion with poor prognosis. Primary intraosseous carcinoma (PIOC) lesion develops either de novo remnants of odontogenic epithelium, odontogenic cyst/tumor, epithelium remnants, or/and salivary gland residues. We describe very interesting case of primary intraosseous carcinoma of mandible. This extensive lesion was sent for oncological opinion and further management. Due to the uncertainty of diagnostic criteria of PIOC, only few cases of this lesion with a typical presentation have been reported. This article presents a case of primary intraosseous carcinoma with a unique appearance and detailed review stating its clinicopathological correlation.

“…[ 1 ] This tumor is affecting commonly the parotid gland (89.6%), submandibular gland (8.4%), and sublingual gland (0.4%). [ 2 ] There are three main cell types in histopathological features of MEC containing mucin-producing, epidermoid, and intermediate cells. [ 3 4 ] Central MEC (CMEC) is a rare primary intraosseous bony lesion with an incidence of 2%–4.3% of all MECs reported.…”

A case of central mucoepidermoid carcinoma associated with dentigerous cyst

Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland neoplasm. Central MEC (CMEC) is a rare primary intraosseous bony lesion with an incidence of 2%–4.3% of all MECs reported. In this article, we present a rare case of a CMEC in the anterior region of maxilla at a 43-year-old female patient that was arising from a dentigerous cyst. CMECs are extremely rare tumor. They are usually low-grade lesions with favorable prognosis. Odontogenic cysts are one of the origins of this lesion. Treatment of impacted tooth is necessary in the early stage for prevention of this neoplasm.

“…Central MECs are uncommon tumors, comprising 2-3% of all mucoepidermoid carcinomas reported 2. They have been reported in patients of all ages, ranging from 1 to 78 years, with the overwhelming majority occurring in the 4th and 5th decades of life 2.…”

“…They are histologically low-grade cancers, usually affecting the mandible as unilocular or multilocular radiographic lesions 3. Other radiographic manifestations of central MECs include mixed radiopaqueradiolucent lesions, destructive osteolytic lesions with ill-defined margins, and radiolucency with calcifications or new bone formation 1,2,3. However, in the present case, the lesion-affected maxilla showed a "ground glass" pattern on conventional radiographs and a destructive lesion with calcifications on computed tomographic (CT) images.…”

Mucoepidermoid carcinomas (MECs) arising within the jaws as primary central bony lesions are termed central MECs. Central MECs are extremely rare, comprising 2-3% of all mucoepidermoid carcinomas. We herein report a rare case of central MEC of the maxilla in a 52-year-old male whose plain radiographs showed a "ground glass" pattern and computed tomographic images, a hypodense mass with numerous calcifications. To the best of our knowledge, this is the first report of central MEC showing a "ground glass" appearance.
