Cutaneous chromomycosis is a slow growing verrucous skin infection caused by five species, identified as Philadophara verruscosa, Fonsecaea dermatitidis, Fonsecaea pedrosoi, Fonsecaea compactum, Cladosporium, carionii. We report a case of chromomycosis of the skin causing by Cladosporium genus, in view of its rarity and unique light microscopic and ultrastructural features. This 65-year-old female had suffered from eczematous and lichenified skin lesion for the last two years since she burned her dorsum of the left hand by boiling oil. The lesion was slowly progressed, and ended up to the brownish hardening of the skin covered with crusts. Skin punch biopsy was done. Histologically, the sections revealed typical features of chronic granulomatous inflammation along with the heavy infiltration of the lymphocytes, plasma cells and histiocytes. Pseudocarcinomatous downgrowth of the epidermis and microabscesses in the upper dermis were also found. Numerous thick walled fungal organisms were noted within the giant cells and freely in the dermis, which were positive ant PAS stain, and diastase resistant. Thick mucous capsule is not observed. The organisms showed very faint yellowish walls with a few buddings and a few short elongated hyphae were also noted. Ultrastructurally, the fungus wall was multilayered and inner organelles were sparse. There is no evidence of systemic involvement, especially brain.

Fibrous hamartoma of infancy (FHI) is an uncommon, benign, solitary intradermal or subcutaneous tumor. It occurs typically in the axillary or shoulder region. The histopathologic examination of affected lesion shows the characteristic elements: dense fibrous tissue, adipose tissue, and primitive mesenchymal tissues. A 15 month-old girl had the multiple, asymptomatic, discrete, and skin-colored tumors that scattered on the scalp. These were present at birth. We report a rare case of FHI occurred on the scalp with multiple and congenital characteristics.

A case of hepatocellular carcinoma (HCC) complicating with secondary biliary cirrhosis due to intrahepatic bile duct growth of the tumor is presented. The patient was 34 years-old male who had been suffered from right upper quadrant pain with intermittent fluctuating jaundice for 4 months. Left lobectomy specimen contained a single, 4 cm sized, relatively well circumscribed and partly protruding nodular HCC in the medial seqment of left lobe. It compressed the left hepatic duct, and the intra and extra-hepatic ducts were completely plugged with tumor casts (extending to the common bile duct at the operating table). Remaining hepatic parenclyma was the seat of advanced secondary biliary cirrhosis in which were abundance of HBsAg-containing hepatocytes possibily representing a HBsAg carrier status. Biliary cirrhosis in HCC is an extremely rare manifestation, reflecting the delayed adequate clinical procedure by unusual pattern of obstructive jaundice. In such a case presenting as persisting and fluctuating obstructive jaundice in HCC, an intrabile duct tumor growth should be suspected.

A case of calcifying synovial sarcoma, occuring in the deep muscle fascia of the left thigh is reported. The presence of extensive calcification in synovial sarcoma is a favorable sign for prognosis. The patient was a 31-year-old female. The tumor mass had been present for 3 years, accompanying local tenderness. X-ray revealed a soft tissue tumor with central calcification, which was located between the adductor magnus and brevis of the left thigh. The tumor size was 7 x 5.5 cm. There was no connection with the knee joint or the femur. Grossly, the tumor was a relatively well circumscribed hard tumor with massive calcification. Microscopically, the tumor was composed of predominantly spindle cells with accompanying hyalinization, numerous spherical concretions and ossification. The epithelial component was not clearly noted. Mitotic figures were rarely noted in the densely cellular area. Immunohistochemical staining for EMA, S-100, vimentin, and carcinoembryonic antigen was negative while vimentin and cytokeratin were weakly and focally positive. EM study revealed multiple desmosome-like calcification intercellular junctions with a slit-like lumen and an incomplete basal lamina, which suggest that tumor show these cells were undergoing epithelia] differentiation. Above evidence suggest that this tumor is a synovial sarcoma associated with a large area of calcification, a so called calcifying synovial sarcoma. No recurrence was noted in one and half years of follow up.
