BACKGROUND Bile cytology from percutaneous transhepatic cholangio-drainage (PTCD) is a useful procedure in case of obstructive jaundice. CASE Repeated cytology via PTCD from a cystically dilated duct in a 56-year-old female with a long clinical history permitted a diagnosis of squamous cell carcinoma (SCC). The smears showed excessive benign-appearing squamous cells with or without a nucleus ...

Introduction: Although cervical carcinoma is common, cutaneous metastasis from this tumor is rare. The reported incidence rates of skin metastasis from cervical cancer range from 0.1% to 1.3%. The major histological subtype of cervical carcinoma is squamous cell carcinoma (SCC), accounting for 75% of cases. The remainder are classified as adenocarcinoma, adenosquamous cell carcinoma, or are of ...

Primary squamous cell carcinoma (SCC) of the thyroid is very rare. There are no reports of metastatic papillary thyroid carcinoma (PTC) converting to SCC in cervical lymph nodes following total thyroidectomy due to conventional PTC. An 86-year-old woman with a remote history of total thyroidectomy due to PTC underwent palliative neck surgery to treat recurrent bleeding originating from a metast...

Dendritic cell (DC) vaccines were generated by apoptotic squamous cell carcinoma (SCC) cells induced by 5-aminolevulinic acid (ALA)-mediated photodynamic therapy (PDT). ALA-PDT-DC vaccine inhibited the growth of SCC in mice, indicating that immunogenic apoptotic cells can activate an effective antitumor adaptive immunity and lead to a DC vaccine-based cancer immunotherapy.

background: non-melanoma skin cancer is the most common malignant tumor in humans. the role of ultraviolet radiation is well-known in the pathogenesis of basal cell carcinoma (bcc) and squamous cell carcinoma (scc). cd10 is a zinc-dependent metallopeptidase known as common acute lymphoblastic leukemia antigen (calla). although cd10 expression has been investigated in some cutaneous tumors, to o...

back ground: the aim of this study was to characterize the immunohistochemical expression of galectin 1, 3, and 9 in normal oral epithelium, oral squamous papilloma, and oral squamous cell carcinoma. materials and methods: immunohistochemical staining for galectins 1, 3, and 9 was evaluated in 8 samples of normal oral squamous epithelium, 15 samples of oral squamous papilloma, and 41 samples of...

Objective: HPV and EGFR expression status may be utilized as an independent prognostic factor owing to the different clinical demographic characteristics head neck cancers. In study, it was aimed investigate association between EGFR, p16 ki67 survival in patients with squamous cell carcinoma (SCC).Materials Methods: A total of 43 SCC region were included study. Ki67 examined by means immunohist...

Background: Carcinomas arising from the gallbladder are highly aggressive tumours with limited treatment options available beyond surgical resection. Squamous cell carcinoma (SCC), including adenosquamous carcinoma, makes up 1–4% of carcinomas which often present at an advanced stage worse prognosis than conventional adenocarcinoma. A pure SCC is even rarer, reported incidence 1% all carcinomas...

CT: computed tomography HNCSCC: head and neck cutaneous squamous cell carcinoma IMRT: intensity-modulated radiation therapy MMS: Mohs micrographic surgery PNI: perineural invasion RT: radiation therapy SCC: squamous cell carcinoma INTRODUCTION Head and neck cutaneous squamous cell carcinoma (HNCSCC) is a growing problem in the immunosuppressed population, and the behavior of these cancers can b...

The KU-8 cell line was established from a lymph node metastasis of human squamous cell carcinoma (SCC) of the penis. The cells grew rapidly (doubling time 20 hours) as adherent monolayers, and were tumorigenic in nude mice. The carcinoma cells showed epithelial characteristics by observation with a phase contrast microscope. The cells retained the ultrastructural characteristics of squamous epi...
