The importance of the ticks in medical field has been emphasized because of their association with and transmission of various diseases. We report herein a case of tick bite in a 55-year-old male farmer, who visited our hospital on July 2, 1981 with a parasite attached on right lower flank and rice to small pea sized, pruritic erythematous papular skin eruptions on chest and right lower flank. The skin lesions disappeared completely with.in five days after removal of the parasite, which was identified with an adult female tick which belongs to Genus Ixodes.

Carcinoma of the breast can produce cutaneous metastases which sbow highly diversified clinical pictures. The cutaneous metastases produce four definite clinical types: inflammatory carcinoma, telangiectatic carcinoma, nodular carcinoma, and carcinoma, en cuirasse. We present a case of 78-year-old nulliparous woman who had several painful dark purplish colored zosteriform papulovesicular eruptions, suggestive of herpes zoster, on the right breast, right axilla, scapular area, and upper arm for three month. Two month later, well dermacated linearly arranged erysipeloid eruptions appeared around the previous skin lesions and the right chest wall. Histopathological findings showed metastatic ductal carcinoma with massive vascular permeation but the primary focus was undetermined.

Reticulate acropigmentation of Kitamura, described first by Kitamura and Akam atsu in 1943, is a pigmentary disorder that may be determined by an autasomal dominant gene. Skin lesions are characterized clinically by depressed brownisL pigmented spots, in a reticulated pattern, on the extensor surface of the acral parts of the extremities. Most reported cases are confined to Japanese. We report herein a case of reticulate acropigmentation of Kitarnura in a 28- year-old woman, with a depressed brownish pigmented spots, in a reticulate pattern, on the dorsum of hands and left foot. The authors make the diagnosis of this case a reticulate acropigmentation of Kitamura for the clinical symptoms and histopathologic findings.

Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.

PURPOSE: This study was attempted to investigate the prevalence of the expression of c-fos protein, TGF-alpha and -beta, PCNA , DNA ploidy pattern and histopathological parameters of giant cell tumor (GCT) of bone and to correlate with prognosis and to extend our understanding on tumorigenesis of GCT. MATERIALS AND METHODS: Twenty eight cases of paraffin-embedded tissue were studied, classified as recurrent (5 cases) and non-recurrent group (12cases) within the limits of the cases which afforded surgical material on first operation. RESULTS: No significant difference was observed in cellularity of stromal cells, atypia of stromal and giant cells, presence of hemorrhage and necrosis between recurrent and non-recurrent group. However, presence of more than 10 mitotic figures in 10 high power fields in recurrent group was significantly higher than non-recurrent group (p<0.05). The immunoreactivity for PCNA was seen only in nuclei of stromal cells, whereas nuclei of giant cells showed negative staining. The positivity of PCNA revealed no significant difference between non-recurrent (mean; 40.9%) and recurrent group (34.4%). The expression of c-fos oncogene was seen in 5 cases (100%) in recurrent group, and 8 cases (66.7%) in non-recurrent group, and no significant difference was seen. No significant difference of expression of TGF-alpha was seen in 5 cases (100%) in recurrent group and in 11 cases (91.7%) in non-recurrent group. The expression of TGF-beta in stromal cells was significantly higher in non-recurrent group (80%) compared to recurrent group (100%) (p<0.05). In DNA analysis out of 18 cases, 4 cases (22.2%) were aneuploidy and 14 cases (77.8%) were diploidy. Among 4 aneuploidy cases, 3 cases (75%) had no recurrence, and 1 case (25%) had metastasis to lung and expired. No significant difference of DNA ploidy pattern was seen between the recurrent and non-recurrent group. CONCLUSION: Presence of more than 10 mitotic figures in 10 high power fields and less expression of TGF-beta are related to higher possibility of recurrence and it is suggested that the number of mitotic figure (more than 10/10HPF) and expression of TGF-beta could be helpful parameters in predicting recurrence of GCT.
