Gastrointestinal stromal tumors account for 0.1-3% of all gastrointestinal neoplasms and are characterized by features that overlap with those of other mesenchymal tumors. We expose the case of a 58-year-old male patient who complained of abdominal pain, weakness and melena. Microscopic examination of surgically resected gastric tumor revealed a neoplastic proliferation composed of spindle cell...

Extraskeletal osteosarcoma is a rare malignant mesenchymal neoplasm and its small cell variant is one among the rarest variant. This article describes a 60-year-old woman presenting with a large, lobulated, painful mass in left thigh with associated history of trauma since 18 months. Her magnetic resonance imaging showed a variegated mixed intensity lesion with associated cystic degeneration, n...

HPV-023 (NCT00518336; ClinicalTrial.gov) is a long-term follow-up of an initial double-blind, randomized (1:1), placebo-controlled study (HPV-001, NCT00689741) evaluating the efficacy against human papillomavirus (HPV)-16/18 infection and associated cyto-histopathological abnormalities, persistence of immunogenicity, and safety of the HPV-16/18 AS04-adjuvanted vaccine. Among the women, aged 15-...

The aim of the study was to development rice microspores in anther culture vitro , structure androclinic callus identify cyto-embryological features formation morphogenic structures culture, obtain doubled haploids ( Oryza sativa L .) and accelerate valuable breeding material with desired properties. Within framework this study, results a cyto-histological haploid androgenesis were obtained, wh...

CONTEXT Cervical cytology continues to be the most appropriate method for investigating cervical neoplasia and its precursors. Greater diagnostic acuity is obtained by combining cytology, colposcopy and guided biopsy methods. OBJECTIVE To analyze the diagnostic acuity of cyto- and histopathological exams and causes of diagnostic error. DESIGN Retrospective study. SETTING A public tertiary...

clinical and histopathological features of basal cell carcinoma (bcc) may differ according to the type of carcinogen involved. bcc arising from radiotherapy treatment has high incidence and its clinical and histopathological features may be different from bccs caused by other carcinogens. the aim of our study was to investigate any possible association between specific histopathological or clin...

Sarcomas account for approximately 1-2% of human malignant disease and are relatively uncommon. Histopathological study of these mesenchymal tumours at light microscopic and ultrastructural level may not always provide an unambiguous diagnosis. It has become apparent with the identification of increasing numbers of tumour specific genetic alterations that (cyto) genetic evaluation could become ...
