Schwannomas are benign nerve sheath tumors that originate from any anatomical site. Most of the schwannomas are found in the head, neck or limbs. Schwannoma arising in a lymph node is extremely rare. We have found only four cases in the review of the literature. We experienced a case of intranodal schwannoma in a perigastric lymph node. A 72 year-old female underwent cholecystectomy due to ...

Introduction: Medullary thyroid cancer (MTC) is an uncommon neoplasm originating from parafollicular C cells. Distant metastasis in MTC, such as axillary node involvement, is extremely rare.  Case Report: The present study describes a known case of MTC with axillary lymph node metastasis in a 31-year-old woman. In 2010, she underwent total thyroidectomy and right-sided modified radical neck dis...

  Introduction: Sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. In Iran, this procedure has not been addressed sufficiently. In this study, we report our experience in this area. Methods: Ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mCi of Tc-99m antimony...

Aim. Secondary tumor rarely develops from epidermal nevus. We present a case of a metastasizing squamous cell carcinoma that developed in a solitary epidermal nevus. Case Report. An 82-years old Japanese female was presented with a red tumor on the left axilla. She reported that the tumor developed in a congenital epidermal nevus. A biopsy of the tumor showed that a well-differentiated squamous...

INTRODUCTION Persistent lymphatic drainage following retroperitoneal lymph node dissection for testicular tumor is an uncommon complication. CASE PRESENTATION We describe a 21-year old man of Caucasian origin who had metastatic non-seminomatous germ cell tumor of the testis, and underwent retroperitoneal lymph node dissection, nephrectomy and partial inferior vena cava excision for a residual...

Based on our experience and a review of the literature, we conclude that superficial, well- to moderately differentiated T1 cancers of the anal margin may be successfully treated with radiotherapy alone or local excision. Stage T2 lesions have a significant risk of inguinal lymph node metastases and should be treated with radiotherapy to the primary tumor in conjunction with elective inguinal l...

With the widespread introduction of population screening for colorectal cancer in Europe, the number of early rectal cancers is expected to increase. In the past, approximately 25 % of rectal cancers presented with early disease, defined as stage I disease. First, results from population screening in the UK demonstrate an increase to approximately 50 % stage I for screen-detected carcinomas. In...

A patient presented with flu-like symptoms and a warm, tender area in the left axilla after working with an ancient piece of Cyprus wood. Antibiotics prescribed failed to improve symptoms. Followup physical examination and subsequent ultrasound found suspicious left-breast mass and an enlarged lymph node in the left axilla. Biopsy and lumpectomy of the left-breast mass revealed invasive ductal ...

Dermoid cysts of the head and neck are rare lesions. An unusual dermoid cyst in the subcutaneous tissue of the mastoid region is easily confused with lymph node abnormalities; therefore, diagnosis and treatment are often challenging. We describe a 22-year-old male with an unusual dermoid cyst in the subcutaneous tissue of the mastoid region whose only complaint was a retroauricular lump, which ...
