Desmoplasia is a highly aggressive histopathologic feature of cutaneous squamous cell carcinoma CSCC independently associated with death from CSCC. It the deposition abnormal collagen around tumor as seen on H&E. However, structure this unknown. Herein, early immunofluorescence (IF) studies to define differences between normal and desmoplastic structures are reported. Tumor samples 27 patients ...

a desmoplastic small round cell tumor is a malignant tumor of the abdominal and pelvic cavities. this tumor involves serosal surfaces such as the peritoneum, pleura, and scrotum. in this case report a 28-year old male presented with a desmoplastic small round cell tumor located in the abdomen along with urological symptoms. when the diagnosis was completed, the patient’s tumor had metastasized ...

Desmoplastic infantile astrocytoma is a rare low-grade malignant brain tumor found in infants. Its pathological diagnosis can be made on the basis of its histological characteristics and immunohistochemical staining. A case of desmoplastic infantile astrocytoma, including its clinical manifestations, pathological characteristics, differential diagnosis, treatment, and prognosis, is reported. Pr...

Conley et al., in 1971, described a special type of melanoma characterized by a superficial melanic lesion at the onset; repeated local relapses as subcutaneous tumorations with an histological picture closely resembling an atypical fibroxantoma or fibrosarcoma. After a review of all the published material the autors presents a personal case with the clinical, histological and evolutive charact...

fibrous, soft-tissue tumor first described by Evans (1) in 1995. This tumor is clinically and morphologically distinct and was deemed completely benign in a few reported series (1-3). There have also been published case reports on the MR features of desmoplastic fibroblastoma (4-8). We herein present a case of desmoplastic fibroblastoma with special focus on the MR findings, because they are di...

A unique case of a metastatic non-desmoplastic sarcomatoid malignant melanoma in an axillary lymph node showing smooth muscle differentiation in a 54 year old woman is described. The tumour cells exhibited alpha-smooth muscle actin, HHF-35 and desmin positivity but were negative for S100 protein and HMB-45. Ultrastructural examination revealed smooth muscle phenotype and there was no evidence o...

Ameloblastoma is usually considered a homogenous neoplasm and is thought of as the most primitive of all odontogenic neoplasms. However, detailed investigations have proven clinicopathological diversity in a significant number of cases, thus mounting the evidence in favor of considering ameloblastoma as a mysterious lesion. The purpose of this article is to report a unique case of desmoplastic ...

Desmoplastic ameloblastoma is an unusual type of ameloblastoma with special histologic and radiographic features and anatomic distribution which differs from those in the classic type of ameloblastoma. The purpose of this article is to assist the dental community in better understanding of this variation of odontogenic tumor. We present a patient with desmoplastic and conventional variant of am...
