1. Anomalies of origination and course • Absent left main trunk, • Anomalous location of coronary ostium within aortic root or near proper aortic sinus of Valsalva (for each artery) • Anomalous location of coronary ostium outside normal "coronary" aortic sinuses • Anomalous location of coronary ostium at improper sinus (which may involve joint origination or "single" coronary pattern) • Single ...

BACKGROUND Multiple eccrine hidrocystomas of de upper lip are bening cystic lesions that are associated with a chronic course. It is reported in the literature as a rare pathology. CASE REPORT We describe the case of a 60-year-old woman who was referred to the dermatology department for presenting multiple lesions translucent papular asymptomic two years of evolution on the upper lip. Increas...

introduction: iatrogenic aortocoronary dissection (acd) is a nightmare in interventional cardiology. although acd is rarely reported, the real-world prevalence is suspected of being higher due to unreported cases. the right coronary artery (rca) ostium is involved in the majority of cases, and dissections are usually limited to the aortic sinus in half of the clinical presentations. there are d...

OBJECTIVES To gather and compare clinical and histologic information from individuals affected by hypohidrotic ectodermal dysplasia (HED) and unaffected control subjects and to assess the value of these data in the diagnosis of HED. DESIGN Volunteer subjects attending the 20th Annual Family Conference of the National Foundation for Ectodermal Dysplasia answered a questionnaire and performed a...

Eccrine syringofibroadenoma (ESFA) is a rare eccrine ductal adnexal tumor. It shows variable presentations as solitary or multiple nodular lesions arranged in different patterns. It is most commonly seen in middle-aged to elderly patients, and most common sites include the extremities. Classic histopathological findings show anastomosing cords and strands of uniform cuboidal cells surrounded by...

Syringomas are benign appendageal tumors originated from eccrine ducts. The lesions usually present as multiple small, firm papules at lower eyelids and cheeks of women. Plaque-type syringoma is an infrequent form of syringoma and to date, 12 cases have been reported. Pathology demonstrated benign proliferation of eccrine ductal structures in the dermis with surrounding fibrotic stroma. We repo...

Figure 1. Right lower back lesion diagnosed as squamous cell carcinoma on previous shave biopsy with final excisional biopsy results of squamoid ductal eccrine carcinoma. DESCRIPTION An 89-year-old man presented with a rapidly progressing lesion of the right lower back initially diagnosed as squamous cell carcinoma (SCC). Excisional biopsy showed primary squamoid eccrine ductal carcinoma (SEDC)...

We report here the case of a man presenting with mucinous eccrine carcinoma (MEC) involving eyelid. This is a rare adencocarcinoma of the skin that originates from the deepest portion of eccrine sweat duct. The aim of our paper is to underline the importance of distinguishing MEC from metastatic carcinomas of the skin, making clinicians aware that what seems to be a harmless benign lesion may b...
