We report a case of carpal tunnel syndrome caused by palmaris profunda. Palmaris profunda is an anatomical variation longus, which runs beneath the transverse ligament and inserts palmar aponeurosis. Only six clinical cases with have been reported in English medical literatures.A 58-year-old man had numbness median nerve distribution his left hand for three years. He visited our hospital because exacerbation development thenar muscle atrophy. Intraoperatively, tendon was found compressed...
The incidence of atypical mycobacterium (AM) infection is 2.71 out a population 100.000. Most were pulmonary and extra counted 3%. Arthritis osteomyelitis caused by AM rare. We successfuly treated two patients with arthritis coused AM.Case 1. A 62-year-old man wrist pain swelling for 6 years, was suspected as having RA. However, treatment RA did not improve his symptom. He received synovectomy 3 times but synovitis recurred. Mycobacterium scrofulaceum cultured from joint fluid. started...
Tumoral calcinosis is a rare disorder characterised by calcification of periarticular soft tissue. Although hyperphosphatemia not always accompanied, it thought to be pathogenetic factor. We report such case tumoral in 17-year-old girl. She had gradually enlarging mass on her back near the right scapula. Plain radiograph computed tomography, and magnetic resonance imaging revealed partially calcified lesion between scapula thorax. Laboratory tests including levels serum calcium parathyroid...
Merkel cell carcinoma (MCC), first described by Toker in 1972, is a rare superficial subcutaneous presumably derived from neurotactile cells of the dermis. Lymph node metastasis frequent, but bone rarely reported. A 66 year-old man was referred showing an osteolytic destructive lesion his right proximal tibia. Simple resection left buttock tumor had been performed another hospital two years previously. Open biopsy revealed small round carcinoma, positive to EMA, NSE, S-100, and negative...
We successfully treated skin defects around the ankle joint by reverse venoneuroadipofascial (V-NAF) flap in 2 patients. The V-NAF is fasciocutaneus supplied accompanying arteries of cutaneous vein and nerve. Case 1 was a 54-year-old female suffering rheumatoid arthritis for 30 years. Intractable ulcer at medial malleolar region right occurred years ago has enlarged. defect covered with (16×6cm) donor site graft.
