Inflammatory pseudotumor is a term given to different neoplastic and nonneoplastic entities that have a common histological appearance, which comprises spindle cell proliferation with a prominent chronic inflammatory cell infiltrate. Inflammatory myofibroblastic tumor (IMT) is an uncommon lesion with distinctive clinical, pathological and molecular features and is considered to be pseudotumor f...

BACKGROUND Ectomesenchymal chondromyxoid tumour (ECT) is a rare, benign neoplasm of uncertain histogenesis, which appears to exclusively involve the oral cavity, particularly the tongue. CASE REPORT We report the case of a 27-year-old woman with a 0.7 cm tumoral lesion of 3 months' duration on the dorsum of the tongue. Histologically, it comprised well-circumscribed, unencapsulated lobular pr...

Acinic cell adenocarcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of all primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and ACC is usually more frequent in women than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. ACCs rarely inv...

OBJECTIVES Tongue is the most important phonatory organ in stomatognathic system. Radical resection of tongue squamous cell carcinoma can cause tongue defect and result in serious oral dysfunction, especially in phonetic function. This study aims to reveal the influence of tongue cancer, tongue defect and tongue reconstructions to phonetic function of tongue cancer patients. STUDY DESIGN Form...

Squamous cell carcinoma is the most common malignant neoplasm of the Oral Cavity, usually affecting individuals over 50 years of age. It rarely occurs in patients who are less than 40 years old (0.4-5.5%). However, since it is so rare, when cases occur they are often misdiagnosed and inappropriately treated leading to delay in definitive treatment. This report describes a case of squamous cell ...

Granular cell tumors (granular cell rnyoblastoma) are neoplasms Which pursue a benign clinical course in large majority of cases. Tongue is the classic location for this tumor, however, rarely it is seen ill many other sites. Cases of granular cell tumor have been described in both male and female breasts The recognition of this entity in breast is important because it mimics breast carcinoma c...

BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is a spectrum of hematological diseases arising in context of immunosuppression after organ transplantation. PTLD can involve any organ; however, it is extremely rare in oral cavity. METHODS Using morphologic and immunophenotypic approaches we have studied a case of monomorphic PTLD of the tongue that developed in a patient follow...

An unusual case of post-radiation primary intranodal leiomyosarcoma of the cervical lymph node is presented. The patient was a 32-year-old white man who was treated in 1986 with hemiglossectomy and right neck dissection, followed by radiation therapy, for squamous cell carcinoma of the tongue. Six years later, he presented with an enlarged left cervical lymph node which on biopsy showed a high ...

Rhabdomyosarcoma (RMS) is a soft tissue neoplasm of mesenchymal origin. It is a commonly encountered malignant tumor amongst pediatric patients, yet relatively rare in adults. It usually involves the head and neck region, genitourinary organs and retroperitoneal structures. In adults, the most commonly affected area is the head and neck region. We present here a case of a 30-year-old male patie...

BACKGROUND To review the demographic data of a series of adenoid cystic carcinoma (ACC) of the tongue, as well as to analyze c-kit expression, histopathologic patterns, prognostic factors, evolution, recurrences and/or persistence and survival. METHODS Retrospective study from 1986 to 2006, which reviews a database of 68 patients with diagnosis of head and neck ACC. RESULTS We found eight c...
