desmoplastic fibroma (df) is a rare and locally aggressive intraosseous tumor with unknown etiology. the mandible is the common site of involvement in the maxillofacial region. however, it is believed that df can arise in any bone of the body. a wide age distribution has been reported for df occurrence, extending from birth to the sixth decade of life, with a peak incidence at 10 to 19 years of...

In 1987, VandenBerg and colleagues [1] reported 11 cases of an apparently distinct clinicopathologic entity: desmoplastic infantile ganglioglioma. The patients were all infants who presented with large tumors that showed evidence of glial and ganglionic differentiation accompanied by an extreme desmoplastic reaction. Routinely, the prognosis was excellent following either partial or complete tu...

We present a case of desmoplastic cerebral astrocytoma of infancy (DCAI) in a 9-month-old boy including immunohistochemical and proliferative activity studies. It was mainly composed of glial fibrillary acidic protein (GFAP)-positive astrocytes and desmoplastic stroma. Studies with Ki-67 and synthetic phase fraction disclosed a low proliferative activity. Flow cytometric study revealed diploidy...

The ameloblastoma is a benign neoplasm of epithelial odontogenic origin, slowly growing, locally invasive and it is the most common odontogenic tumor in the jaws. Histologically, various types have been described in literature. The desmoplastic variant is rare and characterized by difference in the typical findings of ameloblastoma, including localization, radiographic and histological features...

Desmoplastic small round cell tumor is an extremely rare and highly aggressive neoplasm. It usually arises as a single mass or multiple masses in the abdominal cavity, characterized by diffuse peritoneal implants, involvement of regional lymph nodes, and liver and lung metastases. However, bone marrow metastasis has rarely been reported in the literature. We present a case of clinically symptom...

Desmoplastic infantile gangliogliomas (DIG) are uncommon supratentorial brain tumors with a usually good prognosis despite an aggressive radiological appearance that typically occurs in infants below the age of 24 months. DIGs are exclusively supratentorial, generally have a voluminous size, and are partially cystic. Total surgical removal is sufficient for the treatment of these tumors, and no...

malignant melanoma is a potentially aggressive tumor of melanocytic origin. primary oral malignant melanoma is a rare neoplasm, accounting for 0.5% of all oral malignancies. the present case occurred in a 60‑year‑old female patient, as a pedunculated growth involving the palate and alveolar ridge and histologically showing a desmoplastic differentiation. the article discusses the distinct clini...

BACKGROUND Recent studies have suggested that sentinel lymph node (SLN) biopsy is of limited value in desmoplastic melanoma. This study was performed to compare the rate of positive SLN biopsy in the Surveillance, Epidemiology, and End Results (SEER) database with that of a multi-institutional clinical trial and to investigate relevant prognostic factors in desmoplastic melanoma. STUDY DESIGN...

BACKGROUND Adjuvant radiation has been proposed for the treatment of patients with desmoplastic melanoma, who reportedly have local recurrence rates as high as 40-60%. The authors investigated local recurrence rates at a tertiary referral center to determine the success of wide excision alone for patients with desmoplastic melanoma. METHODS A review of a prospectively maintained melanoma clin...
