objective(s):  cd44 is a member of the cell adhesion molecules family. naturally, cd44s, along with cd44v3 influence the cell motility, migration, and adhesion, while in tumor cells they lead to tumor invasion, progression, and metastasis. the purpose of this research is to evaluate the cd44s and cd44v3 expression in esophageal squamous cell carcinoma (escc) and to reveal their correlations wit...

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...

Recent studies suggest that Denosumab reduces tumor size, therefore, makes the surgery easier with lowermorbidity. However, some studies have reported several complications for this drug. So, this systematic reviewwas performed to determine the effectiveness and safety of Denosumab in reducing bone destructions activity ofgiant cell tumor and skeletal-related events (SRE) in affected patients w...

Background: Melanoma is a common and malignant cutaneous tumor, which is responsible for a large proportion of skin cancer deaths. Dendritic cell (DC)-based vaccines have achieved positive results in the treatment of melanoma because of their ability to induce cytotoxic response to facilitate tumor elimination. Objective: To improve the efficacy of dendritic ce...

background and aims. mast cells are one of the characteristic factors in angiogenesis, growth, and metastatic spread of tumors. the distribution and significance of mast cells in many tumors have been demonstrated. however, few studies have evaluated mast cell infiltration in salivary gland tumors. in this study, mast cell counts were evaluated in benign and malignant salivary gland tumors. mat...

background:  giant cell tumor of tendon sheath (gctts) is often thought of as a volar finger mass. we hypothesized that gctts are equally common on the dorsal and volar aspects of the hand. in addition, we hypothesized that there are no factors associated with the location (volar versus dorsal) and largest measured dimension of a gctts.  methods:  a total of 126 patients with a pathological dia...

two rare cases of extra-articular diffuse variant giant cell tumor of the tendon sheath are presented, at the elbow of a 68-year-old female and the foot of a 56-year-old male. both patients presented with a palpable masses and marginal excision was performed; histological sections confirmed the diagnosis of extra-articular giant cell tumor. no adjuvant therapy was administered. at the last foll...

background and objective: histopathological evaluation of granulosa cell tumors (gct) of the ovary may be confused morphologically with a wide variety of the tumors. immunohistochemical staining for inhibin and calretinin can be used for better diagnosis. although it has been suggested that inhibin can be a sensitive marker for gct, it maybe had negative results in some cases.  in addition, cal...

Oral cavity T-cell lymphoma occurs rarely. This case report describes a patient with such a tumor. The case was a 75 years old man presented with a painless swelling on his hard palate mucosa. He had suffered from nose- bleeding and nasal obstruction. Pathology revealed the presence of a T-cell lymphoma tumor in the palate. Though rare, the signs and symptoms of the case suggest that T-cell lym...
