To the Editor, Merkel cell carcinoma (MCC) commonly presents as a malignancy confined to the dermis. Fewer than 10% of cases show varying degrees of epidermal involvement.1 Only a small number of cases of entirely intraepidermal ‘in situ’ MCC (MCCIS) have been reported.2– 8 All but one7 of these cases were encountered as an incidental histopathological finding in the presence of an otherwise co...
skin cancer has a broad and burdensome impact on the health and well-being of iranian and account for substantial health care costs to the nation. the first most common form of skin cancer is basal cell carcinoma (bcc); followed by the squamous cell carcinoma (scc) and the incidence of malignant melanoma (mm) is lower but is fatal. kaposi sarcoma (ks) is a tumor caused by human herpes virus 8. ...
background and objective: basal cell carcinoma (bcc) and squamous cell carcinoma (scc) are two common tumors of the skin. in some cases, distinction between bcc and scc can be difficult. this study aimed to clarify this uncertainty through immunohistochemical analysis. in this respect, epithelial membrane antigen (ema) and ber-ep4 are the two immunohistochemical markers on which we focus in dif...

Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma. The occurrence of BSCC in the nasal cavity is extremely rare. In the present study, two cases of BSCC occurring in the maxillary sinus are reported and the clinicopathological features and immunohistochemical characteristics of this rare tumor are discussed. Two patients, aged 85 (case 1) and 60 years (case 2)...
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.

BACKGROUND Chronic exposure to high concentrations of benzene is usually associated with the development of haematological diseases. However, solid tumors induced by benzene exposure are less frequent.

Background & Objective: Laryngeal squamous cell carcinoma (LSCC) is considered to be one of the most common cancers of the head and neck, accounting for roughly 90% of all malignant tumors of the larynx. To have a timely diagnosis for a better and practical therapy, molecular markers have to be investigated. The aim of this study was to determine the expression of Cyclin D1 (CD...
the association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. from 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the otolaryngology department of khalili hospital, affiliated with shiraz university of medical sciences, shiraz, iran. in three patients, synchronous occurrence of ...
