Chronic sclerosing sialadenitis (CSS) (Kuttner's tumor) is a benign fibroinflammatory condition most commonly affecting the submandibular gland. It presents as hard mass that mimics salivary gland neoplasms. We report an unusual presentation of Kuttner's tumor parotid in order to raise awareness this rare and underreported entity.

Ovarian hemangiomas are benign and rare tumors of female genital tract with less than 60 reported cases in the literature. A 38- yr- old woman was admitted to Be’sat Hospital, Tehran, Iran in 2012, due to severe abdominal pain. Ultrasound evaluation revealed a 6 cm left ovarian cystic mass and serum tumor markers were normal. Then, left salpingo-oophorectomy was performed for the patient. Micro...

 Leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. They produce testosterone leading to hyperandrogenism. We present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra Sonography, and a rise of total and free serum testosterone. An ovarian source of androgen was suspected and a surgery performed. A diagnosis ...

Sebaceoma is a benign tumor with sebaceous differentiation. It usually presents as a yellowish papule or nodule on the face and scalp. This is a report of a 27-year-old-woman who presented with a giant, 6cm×4.5 cm exophytic tumor on her head. Clinically, we considered several diseases; however, the histological and immunohistochemical features matched those of sebaceoma. The lesion was excised ...

Objective: The prime aim of the present study was to analyse the application value of 3.0 T Susceptibility Weighted Imaging (SWI), Diffusion Weighted Imaging (DWI) and Diffusion Tensor Imaging (DTI) sequence in the diagnosis of benign as well as malignant soft tissue tumors. Methods: 30 cases of benign soft tissue tumor and 30 cases of malignant soft tissue tumor (diagnosed pathologically) were...

Background: Shear wave elastography (SWE) estimates the stiffness of a mass based on the velocity of shear wave propagation by sound waves. Due to higher cell density and angiogenesis, malignant masses have higher stiffness than benign ones. Methods: The present study was a prospective study and was performed on patients who were referred to Ahvaz Golestan Hospital with breast mass during Marc...

Malignant transformation of glomus tumor is exceedingly rare and most common reported in lower extremity and abdominal viscera. We could find only 6 previous case report of malignant glomus tumor in the hand. Although large and deeply located glomus tumors are considered to be malignant, evidence has shown that most of these cases were clinically benign. These lesions are better considered as g...

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...

Cerebellar pilocytic Astrocytoma is a benign tumor, acounts for 80% of all cerebellar Astrocytoma, and has a relatively good prognosis. This tumor usually presents with Ataxia and in the case of hydrocephaly with raised intracranial pressure signs such as headeach, and vomiting. Treatment of this tumor is complete resection and if hydrocephally is present V.P. shunt should be inserted. In the c...
