Rhabdoid tumor is a highly aggressive neoplasm of unknown cellular origin in humans, usually occurring in the kidney and central nervous system of infants or children. In older patients, it occurs rarely in other organs, including the skin and soft tissues. A subcutaneous mass in a 13-year-old male mixed-breed cat was composed of nests or sheets of round to polygonal cells with glassy eosinophilic cytoplasmic inclusions. Immunohistochemically, many neoplastic cells expressed vimentin, localized to the cytoplasmic inclusions, whereas the cytoplasm of some neoplastic cells was diffusely positive

Abstract:
ABSTRACT Keratoacanthoma (KA) is a common but underreported tumor of the skin. It is a common cutaneous neoplasm. The most common sites are sun-exposed skin in light-skinned persons of middle age or older. It is considered the prototype of cutaneous pseudo-malignancies. Histopathological verification is done for the diagnosis. The role of radiation therapy and chemical application have not been proven yet. Complete surgical excision is the gold standard for all types of KA.

Abstract Beta7 integrin, a cell adhesion molecule, associates either with the alpha4 or with the alphaE integrin subunit. Alpha4beta7 integrin is expressed on most leucocytes and is essential for their migration to gut-associated lymphoid tissues by interacting with its primary ligand, MAdCAM-1. Although involvement of beta7 integrin in intestinal immunity is well-established, little has been known about the engagements of beta7 integrin in cutaneous immune responses, especially cutaneous anti-tumor immunity. In this study, we injected B16 murine melanoma cells into the skin superficial to the

Abstract:
Background: The differential for soft tissue tumors of the hand and upper limb is broad. Hematologic malignancy remains quite low on the differential for soft tissue tumors involving the hand, and there is little in the literature describing surgical management of such cutaneous manifestations. When the tumor is large or involves the thumb, careful consideration of reconstructive options is required. Methods: We present a rare case of an aggressively enlarging mycosis fungoides, a cutaneous T-cell lymphoma tumor, involving the thumb. This tumor had a history of multiple failed treatment attemp

Introduction. Cutaneous melanoma is one of the most aggressive malignant tumors, and its nodular form with vertical growth is characterized by unfavorable prognosis. However, in the recent years due to advances in basic oncology, a breakthrough in drug therapy of this pathology was made. To a great extent, it is linked to implementation of new therapy with checkpoint inhibitors. The best and longest response rates of cutaneous melanoma to this treatment were achieved compared to other oncological diseases. This fact can be explained by immunogenicity of cutaneous melanoma, high mutational load

Relevance: Cutaneous leiomyosarcoma is a rare primary
 dermal neoplasm, accounting for up to 2-3% of all superficial
 sarcomas. It can occur at any age, most likely between the ages
 of 50 and 70 years. This tumor has a high recurrence potential
 in case of insufficiently deep excision. Recurrent tumors are
 more aggressive and characterized by subsequent metastasis.
 The purpose of the study was to demonstrate the results
 of the histopathological examination of a cutaneous leiomyosarcoma / atypical smooth muscle tumor.

Abstract:
Any cancer can spread to the skin, a phenomenon typically more common in advanced stages of the disease. However, some tumors can remain clinically silent until the discovery of a cutaneous metastasis, often complicating the diagnosis of the primary tumor, especially if it's a rare tumor like breast cancer in men. It is in this context that we report a case of localized cutaneous metastasis on the scalp, without the presence of other associated clinical signs. Investigations revealed a metastatic breast carcinoma requiring extensive surgical intervention, complemented by adjuvant treatments.
