Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...

Congenital epulis is a very rare benign soft-tissue tumor of uncertain histogenesis, which is also known as “gingival granular cell tumor of the newborn”. It occurs almost exclusively as a single tumor along the alveolar ridge of the maxilla in newborn females. Although congenital epulis is strikingly similar to the more common adult granular cell tumor histologically, in contrast to the latter...

among the rare bone tumors, the osteoblastoma is a fascinating tumor. the rarity, the predisposition to occur in any bone and the diagnostic dilemma makes this infrequent tumor interesting. it is sporadically reported in the literature and what is rarer is its occurrence in the pelvis. the unusual location and inconclusive radiographic findings with diffused diagnostic evidences delays the mana...

conclusion serum cyfra21-1 is useful as a measure in differentiating malignant from benign pleural effusion. results there was statistically significant difference between mean of serum cyfra21-1 levels of benign (3.9±7.6) and malignant(19.5± 30) pleural effusion (p=0.01). in addition the sensitivity, specificity, positive predictive value and negative predictive value of serum cyfra21-1 at the...

testicular schwannoma is a very rare benign scrotal tumor. it is a painless mass, but sometimes referred because of pain or sensory losses. tumor markers are normal and radical orchidectomy is its best treatment. here we present an unusual case of intrascrotal schwannoma in a 57 year old man, with a review of the literature.

littoral cell angioma is a splenic vascular tumor of splenic sinus lining cells that is considered benign in general. this report describes a case of littoral cell angioma with no malignant histological features. the lesion is composed of anastomosing vascular channels resembling splenic sinus; they are lined by endothelial cells which show mitotic activity very rare. immunohistochemically, the...

Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...
