ABSTRACT
We reported nine cases of metastatic skin carcinoma experienced at the Department of Dermatology, Obihiro Kosei Hospital during the period from April 1991 to March 1993. Lung was the most common primary lesion (four out of nine cases), followed by uterus (two) and stomach, breast, and kidney (one each). The clinical features of the metastases were classified into nodular (five cases), inflammatory (one case) and sclerotic (three cases) types. Peculiar zoster-like inflammation was seen in metastatic gastric cancer. Pathologically, adenocarcinoma was more common than squamous cell carcinoma. The average interval between the diagnosis of the primary cancers and the development of the skin metastases was about 30±25 months. The average life span after the detection of the skin metastases was 6.8±5.6 months. Poor prognosis of skin metastasis was thus reconfirmed.
ABSTRACT
A 70-year-old man had annular erythema on the area extending from the right scapular region to the right axillary region, where he got tick bites on June 20, 1991. The erythema occurred soon after the bites and spread gradually to become as large as 20 square cm within 25 days. He also felt fatigue. An electrocardiogram revealed an atrioventiricular nodal block. We treated the patient with amoxycillin (750 mg daily) for 35 days. He has been now free from any symptoms over one year. Although repeated serological tests could not detect an antibody to Borrelia burgdorferi, typical erythema chronicum migrans and cardiac manifestation strongly suggested that the case could be diagnosed as Lyme disease.
