metastasis of gastroesphageal junction (gej) adenocarcinoma in skeletal muscle is rare and primary sites for skeletal muscle metastases are usually lung, renal and colorectal cancer. we have encountered with the first case report of solitary psoas muscle metastasis of gej adenocarcinoma. here we describe a 65 years old man was diagnosed with gej adenocarcinoma in tertiary hospital, tehran, iran...

Metastasis of gastroesphageal junction (GEJ) adenocarcinoma in skeletal muscle is rare and primary sites for skeletal muscle metastases are usually lung, renal and colorectal cancer. We have encountered with the first case report of solitary psoas muscle metastasis of GEJ adenocarcinoma. Here we describe a 65 years old man was diagnosed with GEJ adenocarcinoma in tertiary hospital, Tehran, Iran...

rhabdomyosarcomas are the most common soft tissue sarcoma in adult and children that accompany with skeletal muscle differentiation. skin metastasis of rhabdomyosarcomas is unusual and has only been sporadically reported in literature. in this paper we present a case of skin metastasis of rhabdomyosarcoma in an 8-year-old girl that has treated with chemotherapy.

Breast cancer rarely metastasizes to skeletal muscle. Moreover, muscle is a rare site of metastasis for any type cancer. In this study, we report an unexpected finding enlarged mass in the gluteus maximus asymptomatic patient with distant history breast The was observed during computed tomography evaluation preparation non-oncologic procedure. Biopsy and pathological investigation confirmed met...

Colorectal carcinoma is one of the most common causes of cancer-related death, worldwide. Recently, due to the introduction of novel imaging and therapeutic techniques, five-year survival of patients has increased. However, distant metastasis is still expected in half of the patients. Colorectal cancer tends to target the abdominal cavity, liver, lungs, and bones as the common sites of metastas...

pancreatic neuroendocrine tumors (pnet) are uncommon pancreatic neoplasms, accounting for 1-2% of all pancreatic tumors. however, they have a better prognosis and long-term survival compared to exocrine pancreatic cancer. pnets can be divided into functional or non-functional based upon whether or not they excrete active substances relevant to specific clinical syndromes. skeletal muscle metast...

Extracellular vesicles (EVs) have emerged as key players of intercellular communication and mediate crosstalk between tissues. Metastatic tumors release tumorigenic EVs, capable pre-conditioning distal sites for organotropic metastasis. Growing evidence identifies muscle cell-derived EVs myokines potent mediators cellular differentiation, proliferation, metabolism. Muscle-derived cargo other bi...

We read with interest the article by Savas et al. (3 issue, vol. 19, 2015)[1] on hematogenous muscular metastasis of NSCLC in FDG-PET/CT. We would like to ask some queries. First, I would like to know about the definition of “muscle metastasis” used in the article. There might be two kinds of “muscle metastasis”: one with direct metastasis to muscle tissue, and other with muscle invasion from a...

abstract   soft tissue sarcomas of the oral cavity are uncommon malignancies those of smooth-muscle origin are extremely rare. leiomyosarcomas of the tongue are very rare. either surgery or radiation therapy with or without chemotherapy are the treatment modalities which improve prognosis. we are presenting a 32-year-old man with leiomyosarcoma of the lateral aspect of the oral tongue with neck...

The skeletal muscle is an unusual site for metastasis from breast cancer. We present two cases of breast cancer that relapsed as skeletal muscle metastasis without other distant organ metastasis. We performed the core needle biopsy of metastatic sites and confirmed discordance in estrogen receptor, progesterone receptors, and human epidermal growth factor receptor 2 expression between primary b...
