human papillomavirus (hpv) dna has been identified in esophageal carcinomas. however, the incidence of hpv varies significantly in different geographical locations. in this study, neoplasms from turkmen sahra, a region in golestan province in northeast part of iran, with a high incidence of squamous cell carcinoma were analyzed for the presence of hpv dna. turkmen sahra is located in the cancer...

Squamous cell carcinoma of the foot is rare. A case report of occurrence of metastatic squamous carcinoma of the foot with resemblance to verrucous type in an elderly female is presented. This metastatic lesion developed four years after excision of primary squamous cell carcinoma from the left thigh. The patient presented with a painful, exophytic, ulcerated mass on the foot of four months' du...

background: although color doppler ultrasonography (cdus) is useful in the diagnosis of various diseases of the head and neck, flow signals in oral malignant masses are less studied; hence the present study assesses the usefulness of color doppler ultrasonography in quantifying oral squamous cell carcinoma (oscc) vascularization. in addition, we determine the hemodynamic parameters by spectral ...

Primary cutaneous anaplastic large cell lymphoma is a T-cell malignancy with atypical CD30 positive lymphocytes. Pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. Careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...

Ovarian squamous cell carcinoma is usually associated with germ cell tumours (dermoid cyst) or endometriosis in primary cancer. While tumour metastasis to the ovary is common and often bilateral in over 50 percent of cases, metastatic cervical squamous cell carcinoma to the ovary is infrequent compared to adenocarcinoma from other extraovarian primaries and the cervix. We report two cases of un...

PURPOSE To distinguish a metastasis from a second primary tumor in patients with a history of head and neck squamous cell carcinoma and subsequent pulmonary squamous cell carcinoma. EXPERIMENTAL DESIGN For 44 patients with a primary squamous cell carcinoma of the head and neck followed by a squamous cell carcinoma of the lung, clinical data, histology, and analysis of loss of heterozygosity (...

BACKGROUND Primary squamous cell carcinoma of the ampulla of Vater is a very rare type of tumor, and the prognosis is not well known mainly due to a limited number of cases reported. Here, we aimed to report a case with primary squamous cell carcinoma of the ampulla of Vater. CASE PRESENTATION A 54-year-old woman presented with weight loss, jaundice, and pain in the epigastric and right upper...

basaloid squamous cell carcinoma of the esophagus are rare [1–4], while esophageal combined carcinoma is very rare [5]. Most cases of combined carcinoma of the esophagus consist of squamous cell carcinoma, adenocarcinoma, and small cell carcinoma [5]. This is the first report of combined adenoid cystic carcinoma, basaloid squamous cell carcinoma, and squamous cell carcinoma of the esophagus. A ...
