This is a report on a 32-year-old man with a history of two previous melanomas with concurrent plaque-type psoriasis. His history dates to 2009, when he was diagnosed with his first melanoma on the right occiput, Clark's level IV, tumor thickness 1.53 mm, nonulcerated, mitotic index 1/mm(2). He subsequently developed nodal recurrence after an initial negative sentinel lymph node biopsy and was treated with complete lymph node dissection. In 2012, he was diagnosed with a second primary melanoma on the right upper chest, Clark's level IV, tumor thickness 0...

Mucinous carcinomas of the periorbital area are very rare malignant tumors and can be primary or secondary to metastasis. Primary mucinous carcinomas of the eyelid include, most commonly, primary cutaneous mucinous carcinoma with endocrine mucin-producing sweat gland carcinoma being a remote second.[1,2,3,4] To our knowledge, primary mucinous carcinomas of conjunctiva or lacrimal gland elements have not been described in the literature.[5,6] Metastatic carcinoma from visceral sites should also be considered in the differential diagnosis...

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma or parotid gland adenocarcinoma, and it metastasized to the larynx, lung and medial retropharyngeal lymph nodes. This report provides new insights into feline laryngeal diseases which could result in laryngeal metastasis with slight mucosal irregularity alone and without obvious radiographic abnormalities...

Meningioma is a neoplasm of the meninges, which usually occurs in intracranial sites. Extracranial meningioma has been frequently reported in the sinonasal tract and skull bone, often as extension of intracranial meningiomas. Isolated heterotopic meningioma without contiguous intracranial lesion is extremely rare. A 56-year-old woman presented in December 2015 with 2 firm subcutaneous scalp masses; one in the left lateral (temporal) and the other in the left superior (parietal) region. The clinical impression was that of lipoma...

BACKGROUND: Desmoplastic melanoma (DM) is a subvariant of spindle cell melanoma, accounting for less than 4% of all cutaneous melanomas. It occurs later in life and is associated with chronic sun exposure. Desmoplastic melanoma prognosis is considered more favorable than other variants, with lower rates of metastasis and higher survival. Recently, DM has been further subclassified into pure and mixed, calling into question surgical management and patient outcomes as well as viability of current nationwide databases without this distinction...

Merkel cell carcinoma (MCC) is an uncommon relatively aggressive neuroendocrine dermal neoplasm first described in 1972 as a tumor of the sun exposed skin. Although most MCC affect the skin of the head and neck, rare primarily oral mucosal cases have been documented. Merkel cells are nondendritic neuroendocrine cells that are found not only in the skin but also the oral mucosa and give rise to MCC. Neuroendocrine cells may be found as aggregates in organs or as diffuse or isolated cells within organs and their epithelial lining...

Primary large cell neuroendocrine carcinomas of the skin are exceptionally rare and can be diagnosed only when a metastasis from another organ has been excluded. We report the case of a 62 year old woman with a cutaneous papule on the mid-chest which generated a differential diagnosis of vascular lesion and basal cell carcinoma. Following excision, microscopic evaluation revealed a dermal large cell undifferentiated carcinoma, with a brisk mitotic rate and focal geographic necrosis. Mucin production was absent...

We describe an unusual presentation of Merkel cell carcinoma (MCC), a rare neuroendocrine cutaneous tumour. A 59-year-old man presented with a 2-week history of dyspnoea on a background of MCC of the left elbow that was diagnosed after an axillary lymph node metastasis had appeared. He was clinically diagnosed with cardiac tamponade and received urgent pericardiocentesis. Thoracic CT imaging revealed a large infiltrating mass within the inferior aspect of the heart, confirmed to be MCC via immunohistochemistry of the pericardial fluid...

Merkel cell carcinoma is a rare cutaneous tumor with an aggressive clinical course. In most cases it is associated with Merkel cell polyomavirus infection. Exceptionally, the tumor can present as a lymph node metastasis without a discernible cutaneous primary. In this report we present the case of a 42 year-old man with inguinal lymphadenopathy, histologically consistent with Merkel cell carcinoma. Tumor cells expressed immunohistochemically chromogranin-A, synaptophysin and displayed dot-like positivity for cytokeratin 20...

Mixed/biphasic tumors include epithelial-myoepithelial tumors, pleomorphic adenoma, matrix-producing tumors, cutaneous mixed tumors such as chondroid syringoma (CS), malignant mixed tumors (carcinosarcomas), pulmonary blastomas (in lung), and many others. Morphology may show overlap between various mixed tumors. At any particular site, whether these tumors are primary or metastasis from other sites is difficult to determine, more so if primary is unknown or not disclosed. CS is a rare benign mixed/biphasic skin adnexal tumor, considered as cutaneous counterpart of pleomorphic adenoma...

Of the outward manifestations of visceral malignancy, cutaneous metastases are of particular interest for their impact on identification, prognosis, and management of the primary tumor. Their diagnosis is often challenging and requires high clinical suspicion. The infrequency and clinicopathologic variability of cutaneous metastases can impede their recognition by physical exam and even histopathology. This review offers a practical approach to judicious utilization of the full repertoire of clinical and pathologic data in precise characterization of metastases to the skin...

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...

BACKGROUND: Stage IV metastatic melanoma carries a poor prognosis. In the case of melanoma liver metastasis (MLM), surgical resection may improve survival and represents a therapeutic option, with varying levels of success. Laparoscopic liver resection (LLR) for metastatic melanoma is poorly studied. The aim of this study was to analyze the outcomes of LLR in patients with MLM. MATERIALS AND METHODS: Between April 2000 and August 2013, 11 (1 cutaneous, 9 ocular and 1 unknown primary) patients underwent LLR for MLM at Oslo University Hospital-Rikshospitalet and 13 procedures in total were carried out...
