Dendritic fibromyxolipoma is a rare and distinctive soft tissue neoplasm that is considered by many authors as a variant of spindle cell lipoma and characterized by the presence of dendritic cytoplasmic processes, plexiform vascular pattern, and keloidal collagen. It has never been reported in the larynx and hypopharynx. Its rarity and the potential to mistake it as a more clinically aggressive...

extramedullary plasmacytoma (emp) is a rare neoplasm of soft tissue which usually arises in the respiratory tract, nasal cavity, sinuses and nasopharynx. multiple extramedullary plasmacytomas are extremely rare, especially those that are not associated with multiple myeloma.we describe multiple primary emp in a 37 year old man, without involvement of bone or bone marrow. emp usually has a good ...

Kimura disease is a chronic inflammatory disorder that is prevalent among Asians. It rarely affects the upper limbs or paediatric patients. We report a case of Kimura disease with first presentation as a soft tissue mass in the arm mimicking a soft tissue neoplasm with metastasis in a 12 year old Chinese boy.

Schwannoma is a rare benign neural neoplasm derived from Schwann cells of the peripheral nerve sheath. Schwannoma accounts for 25% to 48% of all neoplasm cases in the head and neck region. Oral Schwannoma is an uncommon soft tissue tumor comprising of 1% of all Schwannomas. Tongue is the most common location for oral schwannoma. Occurrence of gingival schwannoma is very rare and less than 10 ca...

Rhabdomyosarcoma (RMS) is the most common soft-tissue sarcoma of childhood. The neoplasm probably originates from pluripotential mesenchyme, and may occur anywhere in the body. Thirty to 40% arise in the head and neck. Imaging studies typically show a homogeneous soft-tissue mass, often with poorly defined margins and permeative bone destruction (1-5). We report an unusual case of embryonal RMS...

Glomangiosarcoma is a very rare type of soft tissue neoplasm. Here we report such a case in the shoulder of a 51-year-old man.

lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. some studies show that less than 1% of lipomas were ossified. we describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. to the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and h...

One of the most recent methods to determine the proliferative activity is silver stained nucleolar organizer region(AgNORs).The purpose of present study is by using mean AgNOR count per nucleus was found to be higher in benign soft tissue tumour as compared to apparently normal soft tissue and found to be statistically significant. An increase AgNOR score in benign, intermediate, malignant soft...
