Clear cell squamous cell carcinoma (CCSCC) is a rare histological subtype of squamous cell carcinoma (SCC) that was originally described in the skin. Here, we report a case of a 66-year-old female patient who presented with a fungating ulcerative mass of the left lateral tongue extending anteriorly
OBJECTIVE
The objectives of the study are: (i) To determine if periodic acid-Schiff (PAS)-Diastase is an effective tool to diagnose DM noninvasively, (ii) to use three different types of staining procedures to identify the staining pattern over the exfoliated cells of normal and diabetic patients,
A rare case of acinic cell carcinoma of minor salivary gland origin within the oral cavity is reported in a 62-year-old woman. These tumors most commonly arise in the parotid gland and follow an insidious course requiring long-term follow-up. The gross and histologic features of the patient's tumor
A very rare case of deciduoid mesothelioma in the pelvic cavity is presented. A 24-year-old woman (gestational stage: 28 weeks and 6 days) was admitted because of a tumor mass in the abdominal cavity. A well-circumscribed and fibrously encapsulated tumor mass was revealed in the Douglas cavity.
A monotypic angiomyolipoma of the nasal cavity in a 34-year-old woman is described. Tumor cells were spindled or epithelioid and contained glycogen and diastase-resistant PAS-positive granules. There were few mitoses, and necrosis was absent, indicating a benign tumor. The stroma was markedly
Five cases of primary synovial sarcoma of the pleura are presented with a discussion of differentiation from other biphasic malignant neoplasms, most notably malignant mesothelioma. The cases have clinical, histologic, and immunohistochemical features consistent with synovial sarcoma of soft tissue.
Hyalinizing clear cell carcinoma (HCCC) is an uncommon tumor that originates in the salivary glands. This neoplasia constitutes less than 1% of minor salivary gland tumors.A 67-year-old female visited the maxillofacial surgery department owing to a smooth, BACKGROUND
Hyaline ring granuloma (HRG) of the oral cavity is an uncommon disorder considered to be a foreign-body reaction resulting from implantation of food vegetable particles. Microscopically, it is characterized by the presence of structures of hyaline rings in an inflamed fibrous tissue
To present the results of surgical treatment of patients with mediastinalpancreatogeniccysts (MPC).There were 5 patients with MPC.Laboratory tests revealed increased blood amylase level by 1.5-2 times in 3 cases, urine diastase In a retrospective study, granular cell tumors in six dogs (Nos. 1-6), three cats (Nos. 1-3), one horse (No. 1), and one cockatiel (Nymphicus hollandicus) (No. 1) and a meningioma with a granular cell component in one dog (No. 7) were examined histologically and immunohistochemically. These tumors
Brenner tumours of various degree of malignancy were investigated by histochemical methods. The cells lining the cystic cavities in the benign Brenner tumours contained various amounts of PAS-positive, diastase resistant secretory material mixed with small amounts of sulpho- and carboxymucin. The
The application of cytomorphologic criteria to the examination of serous effusions allows the reliable diagnosis of malignancy in the majority of cases. One feature observed in tissue fragments previously thought to be indicative of mesothelial origin is the presence of intercellular windows,
A 14 year-old woman was admitted to Tokyo Women's Medical College Daini Hospital complaining of lumps in bilateral breasts and right supraclavicular region. An excisional biopsy of right breast lump was done. Light- and electron-microscopic examination demonstrated abnormal cells containing many
