Atypical fibroxanthoma (AFX) is an uncommon spindle cell neoplasm of the elderly. This case report presents an atypical case of AFX of the scalp 8 years after hair transplantation in a 35-year-old male patient. Possible synergistic effects of previous sun exposure radiation to the scalp, together with the thermal and radiation injury of carbon dioxide (CO(2)) laser, might explain the mechanisms...

Atypical fibroxanthoma (AFX) is a spindle cell neoplasm with low metastatic potential but high tendency to recur after surgery. Because of the rarity of this lesion and its aspecific clinical features, AFX could be easily misdiagnosed and undertreated by many clinicians who encounter them. Dermoscopy represents a valuable tool for easily assessing skin lesions, even though histological examinat...

the suppression of the regenerative chatter phenomenon in turning process via the variation of the frequency and amplitude of the spindle motor excitation is carried out in this research. a programmable inverter is employed for variable periodic excitation of the spindle motor. a set of turning experiments is designed and performed on a number of conical work pieces both in constant spindle spe...

A gastrointestinal stromal tumor (GIST) is a rare malignancy, accounting for only 0.1% to 3% of all (GI) malignancies. Although GISTs are the most common mesenchymal GI tract, they primarily found within stomach, with rectal rarely reported. They may present bleeding, constipation, pain, or palpable mass while some incidentally. The incidence has been on rise, possibly due advancements in diagn...

Intraparotid hemangioma of the children is a rare neoplasm, posing diagnostic dilemma to the diagnosticians as well as treating clinicians. A 2-month-old male infant presented with a diffuse swelling in the parotid region since birth that was gradually increasing in size. The ultrasonography (USG) report was suggestive of a right intraparotid mass of uncertain etiology; whereas magnetic resonan...

INTRODUCTION Mammary-type myofibroblastoma of the soft tissue is a very rare, benign, mesenchymal neoplasm with myofibroblastic differentiation. To date, 20 cases of extra-mammary myofibroblastoma have been described in literature. To the best of our knowledge, this is the largest extra-mammary myofibroblastoma described in the literature, and the first case reported in this location. CASE PR...

Giant cell tumour of bone (GCT) is a benign primary neoplasm of a bone characterised by distinctive clinical, radiological and pathological features. Females are slightly more often affected than males, and the majority of patients present between the ages of 20 and 50. GCT is locally aggressive and produces expansive and lytic lesions, most commonly in the epiphyses of long tubular bones. Hist...

CONTEXT Undifferentiated (spindle cell) carcinomas of the pancreas are rare anaplastic variants of pancreatic ductal adenocarcinoma with a frequency of 2% of pancreatic exocrine tumors. Their clinicopathological features are limited and obtained by few previously case reports. We report a case of undifferentiated pancreatic carcinoma with a rare focal osteochondroid differentiation. CASE REPO...
