Cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of skin neoplasms that vary in presentation, histology, and prognosis. The most common subtype is mycosis fungoides (MF), which can range presentation from patch or plaque stage to tumor stage.1 Early-stage MF typically entails limited disease, without any nodal extracutaneous involvement. Usually, it follows an indolent course, with ...

Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...

We encountered an undescribed histologic feature of papillary urothelial neoplasms: "urothelial eddy", which was histologically reminiscent of squamous eddy of irritated follicular keratosis of the skin. A review of 756 patients with transurethral resection of bladder tumor revealed 10 patients (1.3%) of papillary urothelial neoplasms with urothelial eddies. All cases were male with a median ag...

BACKGROUND Birt-Hogg-Dubé syndrome (BHD) is a dominantly inherited predisposition for development of fibrofolliculomas, trichodiscomas, and acrochordons. Concurrent internal tumors, such as colonic polyps and renal carcinoma, have been described in patients with BHD. OBJECTIVE To evaluate kindreds with familial renal tumors for cutaneous manifestations of BHD. DESIGN One hundred fifty-two p...

A survey was carried out on all canine neoplasms recorded in the registration files of the Section of Pathology of the Veterinary Research Institute at Onderstepoort over a 40-year period from 1935 to 1974. The neoplasms were divided and tabulated into 14 groups according to body systems or tissue types. A total of 3 388 neoplasms were recorded. The 5 most frequently affected body systems were ...

Mastocytoma is one of the most common skin tumours in dogs. It characterised by a specific course, unpredictable behaviour, and prognosis. This tumour dangerous because it mimics external signs other neoplasms, from less-threatening lipoma to cancer. The purpose study conduct pathomorphological verification classification neoplasia dogs diagnosed during clinical examination establish features m...

FEPs in upper respiratory system are reported originating from oropharynx and larynx, rarely nasal cavity. A 57-year-old female presented with polyp-like lesion right septal mucosa adjacent to mucocutaneous junction. The mass was surgically removed, diagnosis FEP made based histopathological revi...
