We report the case of a 56-year-old woman who underwent total resection of a Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH), which was discovered due to a left temporal intracerebral hematoma revealed by aphasia. IPEH is more often localized on cutaneous and subcutaneous locations, intracranial IPEH are rare and only approximately twenty cases have been published to date. These tumors are a benign vascular lesion composed of papillary intravascular proliferation of epithelial cellular associated thrombosis with fibrin deposits responsible for vascular lumen obliteration...

A 13-yr-old male addax (Addax nasomaculatus) presented with locally extensive alopecia, slight erythema, and skin thickening on the medial aspect of the left rear leg between the stifle and tarsus. Cutaneous T-cell lymphoma was diagnosed after histopathology and immunohistochemical staining of representative skin-punch biopsies. No treatment was elected, and the addax was euthanized 3 yr later because of poor body condition, chronic dental disease, and confirmed spread of lymphoma to other cutaneous locations...

Most primary cutaneous squamous cell carcinomas are cured with surgery. A subset, however, may develop local and nodal metastasis that may eventuate in disease-specific; death. This subset has been variably termed high risk. Herein, we review; an emerging body of data on the risks of these outcomes and propose an evidence-based; risk stratification for low-, intermediate-, and high-risk tumors that takes into; account both tumor and patient characteristics. Finally, we discuss a framework for; management of these tumors on the basis of data, when available, and our; recommendations when data are sparse...

An odontogenic cutaneous fistula is a pathological communication between the outer skin surface of the face and the oral cavity. Facial cutaneous fistula is a complication of odontogenic infection that is often misdiagnosed with skin infection. We report a rare case, which was diagnosed as basal cell carcinoma based on the biopsy of skin lesions in the patient who had been diagnosed with odontogenic cutaneous fistula. A 64-year-old male patient presented with a cutaneous odontogenic fistula. The patient had undergone surgical extraction of fistula tract and loose tooth before dermatology or plastic surgery consultation...

BACKGROUND: Skin cancer is the most common type of cancer. Of the 4 million skin lesions excised annually worldwide, approximately 2 million are considered cancerous. In this study, we aimed to describe a regional experience with skin cancers treated by a single senior surgeon and to provide a treatment algorithm. METHODS: The medical records of 176 patients with head and neck non-melanocytic skin cancer (NMSC) who were treated by a single surgeon at our institution between January 2010 and May 2016 were retrospectively reviewed, and their data (age, sex, pathological type, tumor location/size, treatment modality) were analyzed...

Cutaneous metastasis is considered as a hazardous condition depending on the mean survival around 9 months, which usually originates from cancers of the breast, lung, ovary, colon, and rarely from the cervix. The crucial prognostic factor of cutaneous metastasis depends on the period between the primary malignancy and cutaneous metastasis. We report two cases of the unusual presentation of squamous cell cancer of the cervix that developed vulvar and umbilical metastasis in the 5(th) month of primary treatment...

Miltefosine presents antineoplastic activity but high hemolytic potential. Its use in cancer has been limited to treating cutaneous metastasis of breast cancer. To decrease hemolytic potential, we developed a formulation of miltefosine-loaded polymeric micelles (PM) of the copolymer Pluronic-F127. A central composite design was applied and the analysis of variance showed that the optimum level of hydrodynamic diameter and polydispersity index predicted by the model and experimentally confirmed were 29nm and 0...

Mast cell tumors (MCTs) are commonly encountered in dogs and have been reported in cutaneous, conjunctival, oral mucosal, and gastrointestinal locations, but not in an intramuscular location. Medical records at 2 referral centers in the UK were examined to find cases of MCTs in this location. Seven dogs were identified as having an intramuscular MCT by a combination of fine-needle aspirate cytology and computed tomography or ultrasound. None of the dogs had evidence of local lymph node metastasis. Six dogs had no evidence of distant metastasis and surgery was carried out as the primary treatment option...

INTRODUCTION: Squamous Cell Carcinoma (SCC) includes several subtypes and these can be classified according to their clinical behaviours from the least invasive to the most aggressive. Moreover, it is appropriate to analyse their clinicalpathological patterns 1. In light of its wide histopathological variability, we encountered a rare malignant cutaneous lesion: a SCC of a proliferating trichilemmal tumour (PTT) nature. CASE REPORT: We describe the clinical and pathologic findings of an 82-year-old woman, who developed a SCC with areas of trichilemmal differentiation...

DISEASE OVERVIEW: Cutaneous T-cell lymphomas are a heterogenous group of T-cell lymphoproliferative disorders involving the skin, the majority of which may be classified as Mycosis Fungoides (MF) or Sézary Syndrome (SS). DIAGNOSIS: The diagnosis of MF or SS requires the integration of clinical and histopathologic data. RISK-ADAPTED THERAPY: TNMB (tumor, node, metastasis, blood) staging remains the most important prognostic factor in MF/SS and forms the basis for a "risk-adapted," multi-disciplinary approach to treatment...

We present the case of a 35-year-old man who developed a follicular differentiated cutaneous carcinoma with an eosinophil-rich infiltrate and an aggressive clinical behavior. After an in-depth histopathological investigation the diagnosis of trichoblastic carcinoma was made. Over the course of the disease the patient developed a cutaneous in-transit metastasis as well as an axillary lymph node metastasis 18 months after the excision of the primary tumor on his back. Based on a literature review we discuss the different concepts behind the term "trichoblastic carcinoma" and we summarize the clinical and histological details of previously reported cases...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare neuroendocrine skin tumor, which may be related to sun exposure. It can metastasize to lungs, liver and bone, leading to severe morbidity and mortality. Vertebral metastases from MCC are rare. The authors report the tenth case in the literature, a 59-year-old patient with MCC, which was primarily localized in the scalp, and later provoked distant metastasis to the thoracic spinal column. CASE DESCRIPTION: A 59-year-old woman was admitted at our Unit of Neurosurgery with a 4-month history of progressive and severe dorsal back pain, without neurological signs...

Cutaneous squamous cell carcinoma (cSCC) is a malignancy of keratinocyte-derived skin tumor, which is regarded as the second most common skin cancer worldwide. Accumulating evidence has established that microRNAs (miRNAs) can play a critical role in tumor initiation, progression and metastasis including cSCC. Abnormal expression of hsa-miR-142-5p has been elaborated in various tumors. Nevertheless, its expression and function in the development of cSCC remain unclear. In our study, we found that the expression of hsa-miR-142-5p in cSCC cells were greatly overexpressed compared to human benign epidermal keratinocyte cells...

The most of the emergency in dermatology comprise a variety of entities that most are benign in course. However the vasculopathies and vasculitis are not common,but they could represent the 1,9% and 4,4% according to some studies of emergency dermatology department. They become an important diseases which have to identified early to established an appropiate managment and treatment. Some of them are well known as the leukocitoclastic vasculitis, Schölein-Henoch, panarteritis nodosa, ANCA associated vasculitis, giant cell arteritis, cryoglobulinemic vasculitis and antiphospholipid syndrome...

Primary cutaneous adnexal neoplasms are mostly benign in nature; however, there have been reports of malignant adnexal tumors with distant metastasis to lymph nodes. Adnexal cutaneous malignancy with metastasis to the gastrointestinal tract has never been reported. Here, we present a rare case of a man with primary adnexal cutaneous adenocarcinoma who presented with symptomatic anemia secondary to occult gastrointestinal bleeding, found to be from gastrointestinal metastasis of the adnexal malignancy.

BACKGROUND: Regorafenib is an oral multikinase inhibitor that has been demonstrated as clinically effective in patients with metastatic colorectal cancer in phase III studies. Although disease control was achieved in 40% of the pretreated patients with metastatic colorectal cancer in the pivotal studies, radiological response has rarely been reported. Severe adverse events associated with regorafenib are known to occur during the first and second courses of treatment. We present a case of a 62-year-old Japanese patient whose metastatic colorectal cancer has been responding to treatment with regorafenib for 2 years...

An 11-year-old intact male Green iguana (Iguana iguana) was referred for treatment of a probable iridophoroma based on previous cytopathology. A periocular mass was present near the right medial canthus. Computed tomography did not show any sign of metastasis. Clinicopathologic abnormalities included lymphopenia and hyperproteinemia. Cytologic and histologic evaluations of the mass were consistent with iridophoroma. Complete surgical excision of the mass was not possible without removal of the orbit due to local tissue involvement...

Low-grade neuroendocrine tumors (NETs), also known as carcinoid tumor, commonly arise from the gastrointestinal (GI) and pulmonary tracts, but rarely occur in the skin. Cutaneous NET typically occurs as metastases or high-grade primary lesions, called Merkel cell carcinoma. In the few cases described in literature, primary low-grade neuroendocrine carcinomas of the skin (LGNECS) are usually indolent cutaneous nodules, presenting on the head and trunk of elderly patients. LGNECS tumors are histologically similar to its counterparts arising in other anatomic locations...

Pigmented epithelioid melanocytoma (PEM) is a rare cutaneous melanocytic tumor first described as epithelioid blue nevus in patients with the Carney Complex (CC). PEM was among the first established examples of an intermediate class of melanocytic tumors, including atypical Spitz tumors, with frequent metastasis to lymph nodes but only rare extranodal spread. Sporadic and CC-associated PEM are essentially histologically indistinguishable. A subset of PEM shows loss of cytoplasmic expression of the protein kinase A regulatory subunit alpha (PRKAR1A), a tumor suppressor gene mutated in 70% of families with CC...
