72-years-old male patient was admitted to our clinic with a diagnosis of transient ischemic attack. A mildly hemorrhagic lesion diagnosed by basosquamous cell carcinoma was detected. Carotid stent was implanted into carotid artery. Possibility of malignancy in these types of lesions located in the surgical incision area in patients with advanced aged should always be considered, and endovascula...

We describe a case of basosquamous cell carcinoma arising from a 52-year-old Japanese renal transplantation recipient (RTR). In the present case, we investigated the immunohistochemical profiles of tumor-infiltrating lymphocytes, focusing on cytotoxic granules, granulysin-bearing cells and immunosuppressive cells, such as regulatory T cells and tumor-associated macrophages. Our present study su...

Metatypical Basal Cell Carcinoma, also known as Basosquamous Carcinoma is a subtype of Basal Cell Carcinoma. It is similar to Basal Cell Carcinoma for the gross aspect and regional recurrences, but it has the capacity to spread and develop metastasis. This terrible characteristic endangers the life of the patient if it is not readily recognized by the physicians. Herein we present a report of t...

BACKGROUND Early diagnosis of malignancy of eyelids can save the visual system from metastasis. The study was carried out to determine its pattern of prevalence, which will be a milestone for the ophthalmologists to design a clinical strategy for early intervention. METHODS Retrospectively, we studied 155 eyelid cases from 2000 to June 2009 carried out through histopathologic confirmation. Th...

Myxoid melanoma is a rare variant of melanoma, which is characterized by atypical spindle cells and dense mucin deposition in dermis. This tumor is usually seen in elderly people with a similar progress in other variants of melanoma. A 28-year-old male presented to our outpatient clinic with a 6-month history of a slowly growing asymptomatic pink lesion on his arm. Dermoscopic examination revea...

Basosquamous carcinoma (BSCC) is a rare malignancy, primarily composed of basal cells with foci of squamous differentiation. It is considered to be histologically an intermediate type between basal cell carcinoma and squamous cell carcinoma, and is known to have aggressive behaviors. BSCC occurred in a 17-year-old female minipin with a history of surgical excision for a mammary tumor. The right...
