Fine-needle aspiration biopsy (FNAB) has proved to be an excellent diagnostic tool in the initial management of various lesions affecting endocrine organs. Many studies have attested to its high sensitivity and specificity in diagnosing endocrine tumors, especially that of thyroid gland. However, as with other diagnostic tests its effectiveness is highly dependent upon the expertise of the oper...

BACKGROUND There has been an increase in the use of fine needle aspiration cytology (FNAC) for the diagnosis of parathyroid lesions (PLs). Differentiation between a thyroid lesion and a PL is not easy because of their similar features. We reviewed parathyroid aspirates in our institution and aimed to uncover trends in diagnostic criteria. METHODS We selected 25 parathyroid aspirates (from 6 m...

Ganglion cyst is a relatively common lesion resulting from mucoid, cystic degeneration of soft tissues adjacent to a joint space. Aspiration of cyst contents has been increasingly advocated as a diagnostic and, in some instances, therapeutic modality. We report the fine-needle aspiration cytologic (FNAC) findings from seven cases of ganglion cyst. These include the aspiration of thick, gelatino...

An apocrine hidradenoma is a benign adnexal neoplasm, usually covered by intact skin, but may show superficial ulceration and serous discharge. This feature is raising the possibility of malignancy as it was in our case of macroscopically suspicious tumour. We described cytomorphologic features of cutaneous nodule that might be a lead to the cytologic diagnosis of hidradenoma, but primary or se...

In the area of Medicine, infectious diseases constitute excellent examples where early and accurate diagnosis may be essential for obtaining a good therapeutical response. If on the one hand a great part of this group of diseases may be diagnosed through data obtained from clinical history, physical examination and laboratory tests (including microbiological, mycologic, parasitologic, and other...

Mandibular swellings can be caused by many benign lesions of odontogenic or non-odontogenic origin. The most common tumor of odontogenic origin is ameloblastoma which develops from epithelial cellular elements and dental tissues in various stages of development. It is a benign, yet locally aggressive intraosseous odontogenic tumor occurring most often in the mandible followed by maxilla (1). It...

Chondroid syringoma (CS) is a rare, benign, appendageal tumor with diagnostic feature of myxochondroid stroma supporting eccrine and apocrine epithelial structures. The usual presentation is a painless, slowly growing mass, typically located in the head and neck region. It usually affects middle-aged and older male patients. Because of its unremarkable clinical presentation it is often overlook...

background: biloma is a rare abnormal localized accumulation of bile out of biliary tree due to an injury. it has different non-specific clinical features and its diagnosis is based on clinical signs, radiologic findings and chemical analysis of aspirated liquid. considering the non-specific clinical features, early diagnosis and treatment can have an effective role in the decrease of complicat...

background & objective: abdominal cutaneous and subcutaneous nodules are uncommon lesions which may be benign or malignant. majority of the malignant nodules are metastatic in origin and may be the initial presentation of primary malignancy, hence an early diagnosis is important. our aim was to find out the spectrum of lesions (both non-neoplastic and neoplastic) that present as cutaneous a...
