Primary mucinous carcinoma of the skin (MCS) is a rare neoplasia described for the first time by Lennox et al. in 1952 and formally reviewed by Mendoza and Helwing in 1971. It is an uncommon subtype of sweat gland tumor. MCS affects men (58,8%) more than women (41,2%). It tends to occur in more elderly individuals (average 62,6 years, range 8-87 years), although the disease has been reported in...

Introduction Peripheral ossifying fibroma (POF) is a reactive lesion of the oral cavity, usually seen in the gingiva. As POF occurs usually in the gingiva which is close to the periodontal ligament, origin is thought to be from the periodontal ligament (PDL). However POF is not a counterpart of the central ossifying fibroma but a reactive lesion of the gingiva. POF is commonly seen in the secon...

Endobronchial chondromas are rare benign tumors. They may be part of the Carney triad; however, isolated endobronchial chondromas can occur in the larynx, trachea, and bronchi. We report a case of an endobronchial chondroma in a 61-y-old man with an incidental 5-mm endobronchial polypoid lesion at the proximal left main bronchus that was later found to be an endobronchial chondroma. Flexible br...

Isolated gastric IgG4-related disease (IgG4-RD) is a very rare tumefactive inflammatory condition, with only a few cases reported to date. A 48-year-old woman was incidentally found to have a subepithelial tumor in the stomach. Given a presumptive diagnosis of gastrointestinal stromal tumor or neuroendocrine tumor, she underwent wedge resection. The lesion was vaguely nodular and mainly involve...

A man in his 40s presented with an asymptomatic erythematous, infiltrated plaque, topped by multiple papular and nodular lesions on the left shoulder that appeared 8 months prior (Figure 1). The patient reported no systemic symptoms, fever or weight loss. He had significant medical history, denied any recent travels complete clinical examination was otherwise normal, including lymph node areas....

Nodular fasciitis (NF) is a relatively common soft tissue lesion and represents a rapidly growing benign reactive process. Their cause is unknown. Less than 20% occur in children. Lesions in the head and neck region develop more frequently in children than in adults. NF has been reported at various atypical sites. We report a case of nodular fasciitis at the base of the penis in a 4-year-old bo...

Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous malignancy of the elderly and immunocompromised patients. It is occasionally found coexisting with other diseases, such as squamous cell carcinoma, basal cell carcinoma, actinic keratosis, miscellaneous adnexal tumors, and rarely Bowen disease. A 75-year-old woman presented with a 6-month history of an irregularly shaped erythematous p...

We here report the case of a 58-year old female patient with no particular past medical history, presenting with a 5-year history of vulvar pruritis, drought and vulvodynia at the Department of Dermatology. Clinical examination showed diffuse porcelaine lesions at the level of the vulva, with a yellowish hemispheric nodular lesion measuring 1 cm in diameter on the whitish plates and some excori...

BACKGROUND Sclerosing angiomatoid nodular transformation is a benign disorder of splenic tissue and is often mistaken as a potentially malignant entity in the diagnostic process. To the best of our knowledge, this is the first report of sclerosing angiomatoid nodular transformation mimicking metastasis of melanoma in the literature. CASE PRESENTATION A 43-year-old white man presented with a n...
