Spindle cell squamous cell carcinoma: commonly associated with a good prognosis, less often associated with a poor prognosis following exposure to ionizing radiation, trauma or burn Desmoplastic squamous cell carcinoma: poorly differentiated, pleomorphic spindle cells with a dense stromal response N denotes the extent to which the cancer has spread to regional lymph nodes 3. We report a rare case of cystic poorly differentiated squamous cell carcinoma (CPDSCC) of the scalp. Squamous-cell skin cancer is more likely to spread to distant areas than basal cell cancer.

The authors report the rare occurrence of osteoclast-like giant cells (OGCs) and accompanying epithelioid histiocytes lacking overtly malignant features in association with a poorly differentiated SCC occurring on sun-damaged skin. Background: Primary squamous cell carcinoma of the thyroid (PSCCT) is a rare malignancy of the head and neck, with fewer than 60 cases reported in the literature.

Moderately to poorly differentiated squamous cell carcinoma is treatable - these terms refer to the histologic grade of the tumor (how "bad" or "disorganized" it is). Stages of squamous cell carcinoma… Many early empiric chemotherapy trials of CUP included patients with poorly differentiated carcinoma in addition to the more common adenocarcinomas of unknown primary origin, since these patients were assumed to have the same poor response to treatment and short survival It is now clear that some patients with poorly differentiated carcinomas have extremely responsive neoplasms, and some are … Moderately to poorly differentiated squamous cell carcinoma is treatable - these terms refer to the histologic grade of the tumor (how "bad" or "disorganized" it is). Precursor lesions (dysplasia) can be (arbitrarily) separated into mild, moderate, or severe (carcinoma in situ) (see below). Sarcomatoid squamous cell carcinoma (SSCC) of the uterine cervix is a rare malignancy with uncertain pathogenesis and aggressive clinical behavior. 1. 1 While some cutaneous SCC can be relatively indolent, with low‐risk malignant potential, they account for the majority of keratinocyte related metastases and death. Utility and pitfalls of immunohistochemistry in the differential diagnosis between epithelioid mesothelioma and poorly differentiated lung squamous cell carcinoma We recommend the combination of WT1 and calretinin as a positive maker, and the combination of CEA and claudin-4 as a negative marker, for differential diagnoses of SEM and PDSCC. Diagnosis is confirmed via biopsy of the tissue(s) suspected to be affected by SCC. Well-differentiated tumors resemble closely their tissue of origin, whereas poorly-differentiated tumors barely resemble their tissue of origin.
