[Show abstract][Hide abstract] ABSTRACT: Poroma is a benign adnexal skin tumor seen in middle aged individuals with no sex predilection. The acral sites are the most commonly affected regions. Hip or buttock as a location of origin has rarely been reported. We report two cases of poroma, one located on the hip of a 75-year-old man and the other on the buttock of a 60-year-old man.
[Show abstract][Hide abstract] ABSTRACT: Capillary hemangiomas are very common benign vascular neoplasms which frequently occur in the skin and intraoral
mucous membranes. The intravascular variant of this lesion, however, is distinctly uncommon and has been reported
rarely in the English literature. Those reported cases describe this tumor as arising in veins in cutaneous and
extracutaneous sites. Here we report two cases of intravascular capillary hemangioma arising in the skin.

[Show abstract][Hide abstract] ABSTRACT: Usual causes of a papule or nodule in a post-operative site after resection of a skin tumor are residual or recurrent tumor, proliferative scar, or suture granuloma with inflammation and granulation tissue. Inverted or trapped hair, an acquired trichostasis, has not been implicated as a cause in such cases, this is probably the first case reported in literature.
A 31-year-old woman underwent an excision of a ruptured epidermal cyst of the left axilla. One month later, the previous excision site was re-excised secondary to a non-healing, inflamed papule in order to exclude recurrent epidermal cyst formation. Microscopic examination revealed that the cause of the papular lesion was acquired trichostasis, rather than a recurrent epidermal cyst.
A papular or nodular lesion at a postoperative site may rarely be caused by acquired trichostasis and should be considered as one of the differential diagnosis.

[Show abstract][Hide abstract] ABSTRACT: Osteoclast-like giant cells have been noted in various malignant tumors, such as, carcinomas of pancreas and liver and leiomyosarcomas of non-cutaneous locations, such as, uterus and rectum. We were unable to find any reported case of a leiomyosarcoma of the skin where osteoclast-like giant cells were present in the tumor.
We report a case of a 59-year-old woman with a cutaneous leiomyosarcoma associated with osteoclast-like giant cells arising from the subcutaneous artery of the leg. The nature of the giant cells is discussed in light of the findings from the immunostaining as well as survey of the literature.
A rare case of cutaneous leiomyosarcoma with osteoclast-like giant cells is reported. The giant cells in the tumor appear to be reactive histiocytic cells.
[Show abstract][Hide abstract] ABSTRACT: We report a rare case of a dermal nerve sheath myxoma of the left intranasal skin occurring in a 33-year-old female.
A brief review of nerve sheath myxoma and a similar tumor, neurothekeoma, is presented.

[Show abstract][Hide abstract] ABSTRACT: Hemangiomas (angiomas) are benign tumors of blood and lymphatic vessels commonly found in infants and children.
They are usually superficial in nature, localized, and commonly involve the head or neck, although up to one-third may
be seen in the liver. Total or partial regression of these lesions occurs in the majority of cases before puberty. Rarely
has hemangiomas of the foreskin been described.
