Pigmented extramammary Paget's disease (PEMPD) is an uncommon intraepithelial adenocarcinoma and a rare variant of Paget's disease affecting skin that is rich in apocrine sweat glands such as the axilla, perianal region and vulva. It most commonly occurs in postmenopausal women and presents as a superficial pigmented scaly macule, mimicking a melanocytic lesion. The histological presentation is adenocarcinoma in situ with an increased number of melanocytes scattered between the Paget's cells. Therefore, PEMPD may be misdiagnosed as a melanocytic tumour both clinically and histologically. The tumour cells are usually positive for cytokeratin 7, epithelial membrane antigen, Cam 5.2, HER2, and mucicarmine stain while S100 and human melanoma black-45 highlight the processes of reactive dendritic cells. The association between Paget's cells and intratumoural reactive melanocytes is still unclear. We report our first case of PEMPD associated with an intradermal naevus involving the axilla in a 63-year-old woman.

Abstract PDF

Extraskeletal mesenchymal chondrosarcomas (EMCs) are relatively uncommon, and a location in the upper extremity, especially in the shoulder or axillary region, is rare. Furthermore, the radiographic findings of EMCs do not show any features that distinguish them from other neoplasms, and therefore, definitive diagnoses are made based on histological features. EMC is an aggressive tumor with a poor prognosis, and requires wide surgical excision. However, its treatment may involve peculiarities such as a difficulty in obtaining a proper surgical margin in the axillary region or shoulder. In this report, the authors present two rare cases of EMCs in the axillary region.

Abstract PDF

Odontogenic keratocysts are benign intraosseous tumors of odontogenic origin that occur most commonly in the jaw. In particular, they have a predilection for the angle and ascending ramus of the mandible. In contrast, odontogenic keratocysts arising in the maxillary sinus are relatively rare. Two such cases are reported herein. In addition, the English literature that concerns odontogenic keratocysts of the maxillary sinus is reviewed.

Abstract PDF

In this report, we share our experience of a case of maxillo-facial extraskeletal myxoid chondrosarcoma, a very rare location for this neoplasm. In addition, a literature review is provided. The patient, a 61-year-old male, had a maxillary mass encroaching on the nasal cavity. After debulking, the tumor recurred, attaining its pre-surgical proportion in two months. The patient improved clinically with radiation and remained stable for about one year. However, he ultimately developed metastases in his lung which were treated with palliative chemotherapy with a good outcome lasting three months. We could find only eight reported cases of this tumor in the head region of which two are in the maxilla; hence, ruling out other primary sites is mandatory for a patient presenting with a primary head and neck mass. Surgical removal may be complicated because of the location. A combination of surgery and radiation is the management of choice, with palliative chemotherapy in metastasis.

Abstract PDF: Apocrine carcinoma arising from the apocrine sweat glands is a rare cutaneous malignant tumor which occurs predominantly in the axilla of elderly individuals. The typical histologic features of apocrine carcinoma is within a well developed glandular lumina with abundant eosinophilic cytoplasm and evidence of decapitation secretion. In rare instances, predominant signet ring cell features in apocrine carcinoma has been reported. We experienced a case that occured in the right axilla of a 59-year-old. Histopathologic examination showed a solid tumor that extended from the upper dermis into the subcutis, with a delicate infiltrate of epithelial cells. The cells had granular amphophilic cytoplasm, predominantly showed distinct signet ring cell morphology, and were strongly positive for epithelial mucin. Both lysozyme and gross cystic disease fluid protein-15 were identified in the tumor cells. We diagnosed this to be a case of primary signet ring cell apocrine carcinoma of the axilla after several immunohistochemical and clinical evaluations.

Abstract PDF: Inflammatory myofibroblastic tumor (IMT) is a space occupying lesion which is composed of myofibroblasts, plasma cells, and lymphocytes. IMT of the maxillary sinus is rare and its etiology is unknown. We present a case of inflammatory myofibroblastic tumor occurring in the right maxillary sinus of a 57-year-old woman. Radiologically, this tumor was interpreted as malignant neoplasm. On histologic examination, bundles of spindle cells were admixed with inflammatory cells including mature plasma cells and lymphocytes. On the basis of the immunohistochemical findings and ultrastructural features, we recognized that the intervening spindle cells were myofibroblasts. We discussed etiology and prognostic factors of this tumor.

Abstract PDF: Utilization of fine needle aspiration cytology(FNAC) in the diagnosis of odontogenic tumors seems to have little attention. Ameloblastoma is the most common epithelial odontogenic tumor. However, the cytologic findings of ameloblastoma are described recently. We report a case of ameloblastoma diagnosed by FNAC. The aspirated blood-tinged mucoid fluid from maxillary mass showed a few clusters of tumor cells with distinct two-cell population: basaloid cells with palisading arrangement and squamous cells with more abundant and eosinophilic cytoplasm. Nuclear atypism, pleomorphism or mitosis were absent. A few keratinized bodies in the tumor cell clusters and the third component, stellate cells were also characteristic.

Abstract PDF: Dentinogenic ghost cell tumor (DGCT) is an uncommon odontogenic tumor. It is characterized by islands of odontogenic epithelial cells that contain numerous ghost cells and dysplastic dentin. Occasionally, DGCT combines with other odontogenic tumors, such as ameloblastoma. We report here on a 21-year-old female who complained of a tender solid mass in the left maxilla for the 7 month previous to her admission. MRI revealed a relatively well demarcated mass in the left maxilla with heterogenous signal intensity, measuring 3.2 x 2.8 cm, and this mass had invaded the left palate. Microscopically, the tumor was composed of nests of odontogenic epithelium that contained ghost cells and calcification with dysplastic dentin, which is all consistent with DGCT. Localized area showed odontogenic epithelial follicles that had peripheral palisading and satellite reticulum without ghost cells and dentin, and this is consistent with ame- loblastoma. The immunohistochemistry revealed cytokeratins, EMA, S100 and Bcl-2 positivity in areas of the DGCT and ameloblastoma. In the ameloblastoma, Bcl-2 positivity was noted in the palisading basal cells. We concluded that the tumor was an ameloblastoma associated with DGCT.

Abstract PDF: Metastases to the sinonasal tract are infrequent occurrences from primaries below the clavicles. The total number of reported cases to date is less than 100. There is, however, complete unanimity concerning the histologic type of metastatic neoplasm most often encountered. An interesting phenomenon, generally attributable only to breast and renal cell carcinoma, is the late recurrence of the malignant tumor, even 10 or more years after operation. A 61 year-old-male was admitted to ENT due to frequent epistaxis and right facial swelling. CT scan revealed a huge soft tissue density mass I right maxillary sinus with extension into nasopharynx and deviation of nasal septum. The histologic diagnosis was metastatic renal cell carcinoma. He had left nephrectomy because of renal cell carcinoma, 14 years ago. We report a case of metastatic renal cell carcinoma of maxillary sinus in view of rarity, and a brief review of the literature related to this type of tumor is presented.
