A 38-year-old male patient visited our clinic complaining of three skin lesions on the scalp. There were yellowish to brownish, waxy, non-tender, walnut-sized nodules. Hematoxylin and eosin staining revealed amorphous pinkish material deposits in the dermis. The Congo red stain and Dylon stain under polarizing microscopy showed yellow-green birefringence and the immunoglobulin-lambda light chain stain showed a positive reaction. An electron microscopic examination revealed filaments with uniform diameter(6 to 10nm) that were straight and neither branched nor anastomosed. Based on the clinical, histopathological, immunohistochemical and electron microscopical findings, the skin lesions were diagnosed as nodular amyloidosis.

Sepsis refers to the systemic response to serious infection. Patients with sepsis usually manifest fever, tachycardia, tachypnea, leukocytosis, and a localized site of infection. Methicillin-resistant Staphylococcus aureus(MRSA) is a gram-positive, nonmotile, aerobic, catalase- positive coccus, which is resistant to all the B -lactam antibiotics. Cutaneous manifestations in sepsis are maculopapules, nodules, petechiae, ecchymoses, purpurae, pustules, vesiculobullae, hemorrhagic bullae and ulcers. When MRSA is identified in blood cultures and skin tissue cultures, the skin lesions can be considered as cutaneous manifestations in sepsis caused by MRSA. We report two cases with erythematous pustules, petechiae, hemorrhagic bullae and maculopapules caused by MRSA sepsis. MRSA grew in blood cultures and skin tissue cultures.

There are some effective methods for removing layers of skin to improve aging face and dermatologic defects : chemabrasion (chemical peeling), dermabrasion(surgical removal), laserabrasion. Chemabrasion, generally performed with a chemical solution, is most useful for removal of fine facial wrinkles and abnormal pigmentation. The application of chemical caustics, especially TCA (trichloroacetic acid), is known to be an effective and is now commonly practiced to improve the surface of the facial skin that has been blemished by pigmentation, wrinkles, solar damage and certain scars. Trichloroacetic acid is a colorless melting crystal and derivatives of acetic acid which das protein precipitating properties. It has specific odor but there is not systemic toxic effect like a phenol. It has heavy caustic effect on skin and mucosa and cause the coagulation necrosis of the skin and therefore, it must be handled carefully and stored in the proper condition. Especially, moderate to high concentrated TCA solution must be treated by well-trained persons. A 46-year-old woman visited a private clinic for removal of fine wrinkles around the lip. She was refered to our department because of acute upper lip coagulation necrosis which was caused by injection of 35% TCA solution mistaken for lidocaine, which was supposed to be used for anesthesia. At her arrival, cental half of upper lip showed severe coagulation necrosis. The lesion was well discriminated in a few days, then debridement and immediate reconstruction was done using an Abbe flap. Chemical peeling is a relatively effective procedure for improvement of aging skin lesion in a lower cost with a short time operation, if the practitioner has much experience and optimal indication is properly selected. But not so as, side effect and complication may be often ocurred in a mistake and as a result irreversible scars are remained. We experienced a rare case of upper lip necrosis which was caused by TCA injection mistaked for lidocaine in a private clinic and so, We report this case with the results of experiment of rabbit model which was observation of macroscopic and microscopic changes of the abdominal skin of the rabbit injected with serially diluted TCA solution.

Sebaceous carcinoma is an uncommon neoplasm usually associated with ocular adnexa. This malignancy may occur at any anatomic site that contains sebaceous glands. Despite the widespread anatomic distribution of sebaceous glands, extraocular sebaceous carcinoma occurs with far less frequency. We report a case of an 87-year-old Korean woman with extraocular sebaceous carcinoma treated with total excision.

The colorectal cancer frequently metastasizes to the liver, lung, peritoneum, bone, ovaries, and the adrenal glands. Metastasis to the frontal sinus from adenocarcinoma of rectum, however, is extremely rare. We recently experienced a case of metastatic paranasal sinus cancer from adenocarcinoma of rectum in a 66-year-old female patient, and present this case with a brief review of the literature.

OBJECTIVE: This study was performed to determine the relations of glycosylated hemoglobin (HbA1c) and parameters of nerve conduction study (NCS) in diabetic peripheral polyneuropathy patients. METHOD: Prospectively, total 40 patients with non-insulin dependent diabetes mellitus were included in the study. NCS was performed on median, ulnar, posterior tibial, deep peroneal, superficial peroneal, and sural nerves. Distal latency and conduction velocity (CV) of compound muscle action potential (CMAP), distal latency and amplitude of sensory nerve action potential (SNAP) were used as parameters of NCS. Multiple linear regression analysis were used to analyze the relations of HbA1c and parameters of NCS, after adjustment for age, height, weight, and disease duration of diabetes mellitus. RESULTS: HbA1c level had an inverse relation to CV of median motor nerve (beta= 1.272, p<0.01), ulnar motor nerve (beta= 1.287, p<0.01), posterior tibial nerve (beta= 0.982, p<0.05), and deep peroneal nerve (beta= 1.449, p<0.05). CONCLUSION: This study indicates that HbA1c level was inversely related to motor nerve CV, and that sustained hyperglycemia may be involved in demyelination of motor nerves. Analysis of motor nerve CV related to HbA1c is expected to be useful in the follow-up or efficacy study of diabetes mellitus neuropathy as baseline data.
