BACKGROUND We previously reported that talimogene laherparepvec, an oncolytic herpes virus encoding granulocyte-macrophage colony-stimulating factor (GM-CSF), resulted in an objective response rate of 26 % in patients with advanced melanoma in a phase II clinical trial. The response of individual lesions, however, was not reported. Since talimogene laherparepvec is thought to mediate anti-tumor...

The term visceral lymphomatosis has been applied to the condition in chickens in which one or more of the visceral organs contain abnormally large accumulations of lymphoid cells (26). This condition has also been referred to as lymphatic leukosis (13), lymphadenoma (30), lymphocytoma (15), hepato-lymphomatosis (22), hemocytoblastoma (25), lymphosarcoma (36), and has been regarded by many (1, 1...

OBJECTIVES This study is conducted to show the relationship between visceral pleural, lymphovascular, and perineural invasion, and other clinicopathologic characteristics and their significance as prognostic factors. METHODS The clinicopathologic characteristics of 289 patients who underwent a potentially curative surgical resection between 2000 and 2009 in our clinic were reviewed retrospect...

Primary cutaneous mucinous adenocarcinoma is a rare sweat gland malignancy that most commonly occurs in the head and neck region. The histopathological similarities between primary cutaneous and metastasis from primary visceral tumors allow for both an interesting diagnostic dilemma as well as important management considerations with these patients.

Muir-Torre syndrome (MTS) is characterized by the presence of at least one sebaceous tumor and at least one visceral malignancy. Although a wide range of internal malignancies have been reported, the most frequently observed internal neoplasm is colorectal carcinoma. MTS and hereditary nonpolyposis colorectal carcinoma (HNPCC) share many clinical and pathological characteristics and thus may sh...

BACKGROUND Women with metastatic breast carcinoma have a highly variable clinical course and outcome. Intrinsic genetic heterogeneity of the primary breast tumor may play a role in this variability and may explain it in part. Therefore, the authors tested the hypothesis that the characteristics of primary breast tumors are important determinants of prognosis and survival in patients with metast...

Endocrine therapy is an important treatment option for women with hormone receptor-positive (HR+) advanced breast cancer (ABC), yet many tumors are either intrinsically resistant or develop resistance to these therapies. Treatment of patients with ABC presenting with visceral metastases, which is associated with a poor prognosis, is also problematic. There is an unmet need for effective treatme...

Hypercalcemia is a common life-threatening complication associated with several malignancies. Parathyroid-related peptide has been shown to cause hypercalcemia in several solid tumors but rarely in penile cancer. We report a case of penile cancer with hypercalcemia causing metastatic visceral calcification in lungs, liver, and stomach detected on bone scan without significant abnormalities on C...

Solitary fibrous tumors are benign spindle-cell neoplasms, mostly originating from the visceral pleura. They are common in individuals aged 20-70 with no sex predilection. To our knowledge, this is the unique case of the solitary fibrous tumor originating from the accessory parotid gland in the literature.

Malignant glomus tumor, or glomangiosarcoma, is a very rare mesenchymal neoplasm that, when seen, occurs in visceral organs. Despite having histologic features of malignancy, these tumors usually do not metastasize. However, when metastasis occurs, this disease is often fatal. Our report presents the case of a 59-year-old female patient with a highly aggressive and widely metastatic glomus tumo...
