INTRODUCTION: Head and neck cutaneous squamous cell carcinoma (cSCC) often presents with cervical lymph node metastases. Lymphoma is the second most common malignancy in the cervical region, however, it is rarely synchronous with head and neck cSCC. METHODS: We describe the unusual presentation of a patient with small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) and metastatic head and neck cSCC on 18-fluorodeoxyglucose positron emission tomography (18 F-FDG PET/CT)...

Mast cell tumor (MCT) is a frequent cutaneous neoplasm in dogs that is heterogeneous in clinical presentation and biological behavior, with a variable potential for recurrence and metastasis. Accurate prediction of clinical outcomes has been challenging. The study objective was to develop a system for classification of canine MCT according to the mortality risk based on individual assessment of clinical, histologic, immunohistochemical, and molecular features. The study included 149 dogs with a histologic diagnosis of cutaneous or subcutaneous MCT...

Cutaneous squamous cell carcinoma (cSCC), a malignant proliferation of cutaneous epithelium, represents 20% to 50% of skin cancers. Although the majority of cSCCs are successfully eradicated by surgical excision, a subset of cSCC possesses features associated with a higher likelihood of recurrence, metastasis, and death. The proper identification of these aggressive cSCCs can guide additional work-up and management. In the first article in this continuing medical education series, we discuss the incidence, recurrence rates, mortality rates, and risk factors associated with cSCC and review the staging systems used to stratify patients into high- and low-risk groups...

The cytochrome P450 1B1 (CYP1B1) is a heme-thiolate monooxygenase involved in both estrogen biosynthesis and metabolism. For instance, CYP1B1 catalyzes the hydroxylation of E2 leading to the production of 4-hydroxyestradiol that may act as a potent carcinogenic agent. In addition, CYP1B1 is overexpressed in different tumors including breast cancer. In this scenario, it is worth mentioning that CYP1B1 expression is triggered by estrogens through the estrogen receptor (ER)α in breast cancer cells. In the present study, we evaluated whether the G protein estrogen receptor namely GPER may provide an alternate route toward the expression and function of CYP1B1 in ER-negative breast cancer cells, in main players of the tumor microenvironment as cancer associated fibroblasts (CAFs) that were obtained from breast cancer patients, in CAFs derived from a cutaneous metastasis of an invasive mammary ductal carcinoma and in breast tumor xenografts...

Cholangiocarcinomas are the second most common primary liver malignancies. The lymphatics are the common route of metastatic spread for cholangiocarcinomas. The most frequent sites of metastasis are the liver, abdominal lymph nodes, peritoneum and lungs. Cutaneous metastasis of cholangiocarcinoma is rare, and most commonly occurs following percutaneous biliary drainage. Brain or skull metastases from this tumor are uncommon. However, these rare metastatic lesions may occasionally be the first disease manifestation, although scalp recurrence following curative treatment is uncommon...

Importance: Previous studies have shown that the AJCC Cancer Staging Manual, 7th edition (AJCC 7), tumor classification for cutaneous squamous cell carcinoma (CSCC) failed to accurately stratify disease-related outcomes. The recently released 8th edition (AJCC 8) features a revised tumor classification for only head and neck CSCC (HNCSCC). Objective: To compare AJCC 7 and AJCC 8 tumor classifications for HNCSCC and to validate AJCC 8. Design, Setting, and Participants: This was a 10-year retrospective cohort study (2000-2009) at an academic tertiary care center reviewing 680 primary HNCSCC tumors in 459 patients...

OBJECTIVE: Marjolin's Ulcer (MU) is a rare cutaneous neoplasm arising in cikatrical tissue. Due to its typical clinical presentation as a non-healing lesion in scar tissue, the diagnosis can be delayed and even overlooked. METHODS AND RESULTS: We present the case of an elderly woman who developed an ulcerated, exophytic lesion in a split thickness skin graft (STSG) on the lateral aspect of the left knee. Histology showed a radically excised highly differentiated squamous cell carcinoma (SCC) with keratine pearls and a component of basocellular carcinoma (BCC)...

Transitional cell carcinoma (TCC) arising from renal pelvis rarely gives rise to cutaneous metastasis. Due to the insufficient literature, the exact incidence is not known till date. Moreover, the diagnosis is confirmed on histopathological examination with the aid of immunohistochemistry wherever needed. We are presenting a case of a 70-year-old female with metastatic TCC from the renal pelvis to the abdominal skin, which was diagnosed on cytology alone along with the cell block preparation. We also highlight the important cytomorphological and immunohistochemical features noted, which need to be known to avoid any diagnostic delay...

Background: Periampullary neoplasms include carcinomas of the duodenum, ampulla of Vater, distal common bile duct, and pancreas. The aggressive course of these neoplasms is attributable to the delay in diagnosis, as patients have no symptoms until advanced stages of the disease. More than half of patients have distant metastasis at the time of diagnosis. The most frequent sites of metastasis are the liver, lymph nodes, peritoneum, lung, bone, kidney, and, rarely the skin. Case Report: We report the case of a 45-year-old female patient with adenocarcinoma of the ampulla of Vater metastasizing to the right parietal skull with overlying cutaneous involvement 1 year after a Whipple procedure...

Merkel cell carcinoma (MCC) is an uncommon primary cutaneous neuroendocrine cancer. It most commonly presents as an indurated plaque or nodule on sun-damaged skin in elderly patients and is characterized by high rates of local recurrence and nodal metastasis. Survival at five years is 51% for local disease and as low as 14% for distant disease, which underscores the aggressive nature of this tumor and challenges in management. Advances in immunology and molecular genetics have broadened our understanding of the pathophysiology of MCC and expanded our therapeutic arsenal...

Leiomyosarcomas are sarcomas that originate within smooth muscle cells and generally occur in older patients. These tumours account for 10% of all soft-tissue sarcomas. Metastases occur most commonly to the lungs, kidneys, and liver. Cutaneous metastases may also occur but are usually a very rare and late event. We present a case of a 46-year-old woman who developed subcutaneous metastasis to the axilla, arm and breast after surgical resection of the primary tumour. The patient maintained controlled disease with surgical resections and clinical follow-up, initiating chemotherapy one year after the diagnosis of metastatic disease...

We present a case of carcinoma en cuirasse as a presentation of advanced lobular breast carcinoma. On further investigation, she was found to have metastasis to her liver and bone. We report this case to highlight the phenomenon of cutaneous metastasis. It is important to consider this diagnosis as an initial manifestation of breast cancer, but rarely, it can also be associated with other adenocarcinomas, for example, carcinoma of lung, kidney or gastrointestinal tract.

Aggressive digital papillary adenocarcinoma (ADPA) is a rare cutaneous tumor with sweat gland differentiation. Due to the high risk of local recurrence and delayed metastasis, the wide local resection of the primary lesion and long-term follow up are recommended for ADPA. Here, we report two cases of ADPA. Case 1 had a blue-gray nodule on the tip of the right middle finger. Case 2 had had a papule on the dorsal side of the left ring finger for 13 years. In both cases, papillary proliferations of the tumor cells showed multilobular adenomatous structures with back-to-back patterns characteristic of ADPA...

Low grade glioma (LGG) is a very common primary brain neoplasm with a very good prognosis and the median survival of patients is approximately 8 years. With the development of current treatments such as surgery resection, radiotherapy, and chemotherapy, the recurrence rate and the distant metastasis rate of LGGs are largely decreased. Extracranial metastases are seldom happened. However, the authors present a pathologically proven patient with scalp metastasis, which was metastasized from LGG occurring site to the surgical scar 8 months following initial craniotomy and chemotherapy...

Cutaneous metastases from colorectal cancer are extremely rare and generally appear several years after diagnosis or resection of the primary tumor. Although this phenomenon is uncommon, it is very important and often indicates a poor prognosis. We present a case of a 76-year-old female patient with multiple cutaneous metastatic nodules on the back, just 1 month after resection of rectal cancer. Unfortunately, the patient gave up the follow-up treatment due to her age and poor physical condition; she died 3 months later...

BACKGROUND: Merkel cell carcinoma MCC) can present as a cutaneous tumor or a lymph node without primary tumor MCCWP). MCCWP can be misinterpreted on histologic examination as lymph node metastasis LNM) from other neuroendocrine carcinomas LNMNECs). However, this distinction is crucial for therapeutic management. OBJECTIVE: To determine the discriminative criteria for differential diagnosis between MCCWP, LNM from cutaneous MCC and LNMNECs. METHODS: Clinical, morphologic, immunohistochemical data expression of cytokeratin AE1/AE3, 7, 19, 20; chromogranin A, thyroid transcription factor-1 [TTF-1]) and presence of Merkel Cell Polyomavirus MCPyV) immunohistochemistry and PCR) were compared in patients with MCCWP n=17), LNM from cutaneous MCC n=11) and LNMNEC n=20: lung, n=8; thyroid, n=7; digestive tract, n=3; other, n=2)...

Three dogs (Boxer, Labrador Retriever and German Shepherd) between the age of 7-10 years were presented with the history of tumour masses on right caudo-lateral thigh, right cranial forearm and left cranial and caudal thoracic mammary gland region, respectively. Fine needle aspiration cytology of the tumour masses and the sentinel regional lymph nodes were done. Plain radiography was done to rule out distant metastasis. In all the three cases the tumour masses were large in size, firmly adherent to the tissues underneath and sufficient loose skin was not available to close the skin defect following surgery...

BACKGROUND: Cutaneous metastases represent 2% of all skin tumours. Their recognition can be challenging, as they may present with different clinical features, with consequent frequent delay and failure in diagnosis. OBJECTIVES: To review our series of cutaneous metastatic lesions, analyse their frequency according to patient gender, histotype, localization of the primary tumour, and site of cutaneous metastasis, and correlate this data with clinicopathological parameters...
