Multiple trichoepithelioma is an uncommon skin disease with autosomal dominant transmission. A 21-year-old female ahd asymptomatic, flesh-colored, firm papules and nodules on the face, chest and back. Histopathologic examination showed multiple horn cysts and tumor islands composed of basaloid cells.

Localized primary cuteneous nodular amyloidosis is the rarest form of the cutaneous amyloidosis, which appears as single or multiple nodules on the extremities, trunk, genitalia or face. A 44-Year-old woman had asymptomatic, translucent brown to pink papules and nodules on the toes for 5 years. Histopathologic exarnination showed deposition to pale, eosinophilic, amorphous material throughout the dermis, Under the electron microscope, the material consisted of straight, nonbranching, nonanastoimosing filaments. We thus made the diagnosis of nodular amyoidosis.

We report a patient with a cutis laxa-like, generalized PXE without systemic involvement. A 28-year-old woman had loose, pendulous skin of the neck, axillae, thighs, trunk and body folds which resulted in a prematurely aged appearance. She had no family history of related diseases. Histological examination showed considerable accumulations of swollen and irregularly clumped fibers in the middle and lower dermis and von Kossa s stain revealed calcium deposits along the altered elastic fibers.

Livedo reticularis is a mottled bluish discoloration of the skin which occurs in a netlike pattern and is not a diagnosis in itself, but is a nonspecific reaction pattern. It may be classified as idiopathic and secondary livedo reticularis. Decompression sickness can occur during decompression after diving into deep sea water or during a rapiid ascent from sea level, and is one of the many causes of the secondary livedo reticularis. We report a case of livedo reticulris which developed in a patient with decompression sickness. A biopsy from the purpuric patch revealed an unusual histopathologic finding that resembles those of bullae and sweat gland necrosis in drug induced coma.

The cumulative incidence of breast cancer in Korea is low, being about one-fifth of that in the United States. This low incidence has been mainly explained by environmental factors, and recently, however, racial variations in the disease-causing genes should also be considered. The BRCA1 is one of the common genes involved in early-onset breast cancer and/or ovarian cancer in the United States and Northern Europe. However, the involvement of BRCA1 in Korean'breast cancer patients are still unclear. We performed germline mutation screening of the BRCA1 gene by DNA single strand conformation polymorphism (SSCP) analysis. We examined 27 breast cancer patients who were diagnosed less than 35 years by age including two cases with family history of breast cancer. Our study showed no germline mutation at the exons 2, 11 and 20, which were known as the supreme susceptible regions of BRCA1 mutations. Even though our cases did not fulfilled the criteria of familial breast/ovarian cancer, the proprotion of families who inherit the mutated BRCA1 allele seems to be very small and might be negligible among Korean population. Therefore, it is considered that the BRCA1 itself cannot be a major susceptibility gene and the contributions of other genes might be important for the breast cancer.
