ABSTRACT
Transepidermal elimination is a spontaneously-developed phenomenon in certain skin disorders, in which altered connective tissue or foreign material is expelled via the epidermis to the exterior. We report a case of a 60-year-old man with a 1x1 cm sized, black-colored nodule, showing transepidermal elimination, on the right shin. Histological examination revealed a pigmented, epidermal cyst, containing deposition of pigment in its wall and cavity. To the best of our knowledge, no pigmented epidermal cysts have been reported in korea to date.

This study examined the net changes in temperature at various regions of the lower extremities in an attempt to identify the regions demonstrating the most significant temperature changes following a lumbar sympathetic ganglion block (LSGB). Thermography was performed before and after the LSGB in 26 sympathetic nerve system disorder cases. The inspection points were the anterior and posterior surfaces of the thigh, the knee and leg, and the dorsal and plantar surfaces of the feet. The net increases in skin temperature following the LSGB (deltaT (net) ) at the plantar and dorsal surfaces of the feet, were 6.2 +/- 2.68 degrees C (mean +/- SD) and 3.9 +/- 1.89degrees C, respectively, which were higher than those observed in the other regions of the lower extremities (p < 0.05). The areas, in order of decreasing deltaT (net), are as follows: the plantar surface of the foot, the dorsal surface of the foot, the shin, the anterior surface of the knee, the calf, the posterior surface of the knee, the anterior surface of the thigh, and the posterior surface of the thigh. There was one case of orthostatic hypotension during the thermography procedure. In conclusion, thermographic imaging is a useful method for demonstrating the success of a LSGB in various diseases. An evaluation of the deltaT (net) on the plantar surface of the feet using thermographic imaging is the most effective, simple, and safe method for assessing a successful LSGB.

The isomorphic response of Koebner is a well-known phenomenon commonly associated with psoriasis, but it has been also described in conjuction with a host of other disorders. However it has seldom been associated with necrobiosis lipoidica diabeticorum, a rare skin manifestation of diabetes mellicuts. In this report, we describe a 59-year-old woman who developed necrobiosis lipoidica diabeticorum on the left shin where a mosquito had bitten her 2 months ago. Four months ago, she was diagnosed as necrobiosis lipoidica diabeticorum on the right forearm and shin by biopsy and the lesions were improved with corticosteroids intralesional injection. The lesions were asymptomatic and had grown slowly. Histopathological findings showed a large palisading granulomas composed of histiocytes, epithelioid cells and areas of necrobiosis of collagen with multinucleated giant cells. Van Gieson stain showed decreased and fragmented elastic fibers and there were no deposits of mucin in the necrobiotic areas. The lesions were improved with triamcinolone acetonide intralesional injection and there was no recurrence during 4 months.
