+3Previously known as mammary analogue secretory carcinoma (MASC), Secretory Carcinoma is a primary salivary gland tumor that harbors specific ETV6 genetic rearrangement, most commonly ETV6-NTRK3 translocation t(12;15)(q13;q25).This tumor shares similar morphological, immunohistochemical and molecular features as secretory carcinoma of the breast.
It predominantly (76%) occurs in parotid, minor salivary glands of oral cavity and submandibular gland. Variable microscopic arrangements are seen in the microscopy of the tumor, including macrocystic, microcystic, solid, tubular, follicular and papillary cystic patterns.
This tumor is generally low grade with indolent clinical behavior; however, local lymph node metastases may be seen in up to 22%. Rare high grade transformation with aggressive clinical behavior, including distant metastasis was also observed in some patients.

+751-year-old woman complaining of difficulty breathing due to a painless, slow-growing mass on her palate.
Computed tomography showed destruction of the palatine cortex and floor of the nasal cavity with widening of the periodontal ligament.
Histopathological evaluation demonstrated a non-encapsulated tumor composed of small, uniform cells with minimally hyperchromatic nuclei, slightly enlarged nucleoli, and clear to eosinophilic cytoplasm. Solid nests of tumoral cells and numerous small single-layered tubules in minimal intervening stroma is evident.
Dx: Polymorphous Adenocarcinoma

+7A 30-year-old male with a swelling over left side of parotid region.
Th CT images showed well defined lobulated heterogeneously altered signal mass lesion in the left parotid gland, which redominantly involves the superficial lobe of left parotid gland and also extends in the deep lobe.
In microscopic examination there is a partially encapsulated tumor composed of ductual structures and myoepithelial cells in different mesenchymal elements such as myxoid, cartilaginous and hyalinized stroma. The boundary between epithelial and mesenchymal components is blurred by proliferation of myoepithelial cells that have plasmacytoid appearance in some areas.

+6Oral Mucocele (Also Mucous Extravasation Cyst) is a swelling of connective tissue consisting of a collection of fluid called Mucus. This occurs because of a ruptured salivary gland duct usually caused by Local Trauma. Although these lesions are often called Cysts, Mucoceles are not True Cysts because there is No Epithelial Lining.

+5A 73-year-old man complaining of bilateral painless swellings in his neck for 4 years. The first evidence of the tumor was on the right side and it was felt on the left after 1 month. This patient had been smoking 20 cigarettes a day for 30 years. CT scan showed bilateral enlarged parotid glands with uneven density.
Tumor resection and regional superficial parotidectomy were performed bilaterally.
Microscopic examination showed a well-circumscribed tumor composed of epithelial and lymphoid components. Two-layered ductal epithelial cells arranged in the form of papillary structures protruding into cysts spaces was observed. Lymphoid stroma displaying germinal centers was also evident.
Dx: Papillary Cystadenoma Lymphomatosum

+7A 45-year-old man with a history of a painless growth on the right side of the palate that had gradually enlarged in the past year.
Intra-oral examination revealed a well-defined ovoid ulcero-proliferative growth that was non-tender, firm in consistency, and fixed to the underlying bone.
Panoramic radiograph showed a well-defined radiolucent shadow exactly over the right maxillary sinus.
The CT showed a faintly enhancing lesion, in the soft tissue of the hard palate to the right of the midline, associated with slight thinning of the underlying hard palate.
Histopathology slides showed areas of cystic spaces lined with mucous cells (Positive for Mucicarmine Staining) and intermediate cells. Sheets of proliferating epidermoid cells containing nests of large clear cells with cellular pleomorphism, atypia and prominant mitotic figures are also evident.
Dx: Mucoepidermoid Carcinoma

+3The cribriform pattern in Adenoid Cystic Carcinoma is characterized by invasive tumor islands and multiple holes (Pseudocyst) punched out in a Swiss cheese" or Sieve-Like Pattern.
The pseudocysts are sharply demarcated from the surrounding cells and may contain basement membrane material.
The cribriform pattern is unmistakable in this tumor but not always present.

+7A 70-year-old male patient presenting with a painful mass in the hard palate.Panoramic image showed a mass on the right side of the maxilla.
The CT of the head and neck showed the palatal lesion extends to the soft tissue of the buccal mucosa,into the right orbit, anterior part of the cavernous sinus as well as into the sphenoid sinus.
The mass was inoperable and the patient was treated with radiotherapy.
Histopathologic slides revealed uniform, bland population of cells with basophilic nuclei presenting in tubular and cribriform patterns.Two layered gland structures and multiple pseudocysts punched out in a "swiss cheese" pattern was observed. Perineural invasion of tumoral cells was also detected.
Dx: Adenoid Cystic Carcinoma

A 32 year-old female with a well-defined and multilobulated mass in left palatal area and vestibular regions.
The Patient was under orthodontic treatment and had noticed and complained of intraoral bulking for at least 9 months which increased progressively and caused facial asymmetry.
Panoramic view revealed a small radiolucent area at the level of the left premolars.
In CT scan it was observed that this osteolytic lesion affected the vestibular cortex as the palatal bone.
Microscopic examination revealed mature hyaline cartilage, hypercellularity, nuclear and cellular pleomorphism, and multinucleated cells, with significant vacuolization. The tumor cells had a circumscribed multilobular pattern, with focal areas of infiltration into the surrounding bone tissue. The focal presence of a component of small ovoid, hyperchromatic, and undifferentiated cells was observed, interspersing the cartilaginous lobes; osteoid matrix formation was absent. S-100 and Ki-67 markers were positive whereas the pan-cytokeratin AE1/AE3 was negative.
Dx: Chondrosarcoma

+1Osteosarcoma (OS) is a rare tumor arising from immature bone forming cells or through neoplastic differentiation of other immature mesenchymal cells into osteoblasts.
Aggressive clinical behavior, osteolytic areas in the radiograph and histological presentation of malignant mesenchymal cell products such as chicken-wire calcification along with areas of tumor osteoid matrix implies the diagnosis of OS.
Dx: Chicken-wire Calcification in Osteosarcoma

Panoramic view showed a poorly-defined radiolucent lesion with irregular PDL widening and destruction of lamina dura in premolar area.
Computed tomography (CT) revealed mixed radiolucent and radiopaque lesion with ill-defined borders, destruction of buccal and lingual cortical plates invading soft tissue and also maxillary sinus.The characteristic "Sun Burst" appearance was also noted.
Microscopic examination revealed a neoplastic tissue composed of highly pleomorphic cells with bizarre nuclear and cytoplasmic shapes showing numerous mitotic figures arranged in diffuse sheets with prominent osteoid matrix production( Chicken-Wire Pattern)and Chondroblastic Differentiation.

Intra-oral examination revealed a painful ulcerative mass extending in buccal and lingual vestibule.
Panoramic radiography revealed an ill-defined irregular radiolucency without a corticated margin, extending in posterior part of mandible above the lower border, involving the alveolar canal.
Histopathogic examination showed a typical βstarry skyβ appearance with an infiltrate of small neoplastic lymphoid cells with scattered macrophages, positive for CD20 and MYC. High labeling index with prominent nuclear staining for Ki67 was also noted.

+1The hallmark of Burkitt lymphoma is the presence ofa "starry sky" appearance imparted by scattered macrophages phagocytizing cell debris and apoptotic cells among monotonous population of medium sized lymphoid cells.
The tumor cells in Burkitt lymphoma generally strongly express markers of B cell differentiation (CD20, CD22, CD19), as well as CD10 and BCL6. The high mitotic activity of Burkit lymphoma is confirmed by nearly 100% of the cells staining positive for Ki67
