RESUMO
Cutaneous metastasis is rare but may indicate an advanced internal malignancy or a recurrence of a previously treated one and is usually associated with a poor prognosis. They may also pose a diagnostic problem as the clinical manifestations are variable and non-specific, which could mimic other benign conditions. We report a case of a 48-year-old female who presented with a 4-year history of erythematous papules and vesicles on the trunk mimicking lymphangioma circumscriptum. Skin biopsy and immunohistochemistry were consistent with cutaneous metastasis from breast carcinoma. Cutaneous metastasis presents in a variety of patterns. A high index of suspicion and a low threshold for skin biopsy are paramount to the early diagnosis and treatment. A histopathologic evaluation will help identify the origin of the cutaneous metastasis and can significantly affect the outcome of the treatment.
RESUMO
OBJECTIVE: Malignant wounds develop when neoplastic cells invade the skin either locally or by lymphatic and haematogenous spread. They can present as hard-to-heal wounds and underlying causes include: primary skin cancer; metastasis of extracutaneous primary malignancy; malignant transformation of a hard-to-heal wound; iatrogenic injury; and cutaneous forms of cancers of non-skin origin. High clinical suspicion for a malignant wound should be confirmed with skin biopsy. The aim of this case series is to highlight a combination of both clinically clear cutaneous malignancies and not-so-obvious wounds caused by malignancy. METHOD: This case series examines patients with malignant wounds of varying aetiology and appearance. For each case, we explain the pathophysiology, atypical features, diagnostic approach and treatment. We also discuss types of wound biopsy and general wound management principles. RESULTS: Among the 11 cases analysed using descriptive statistics, median wound duration before presentation at our clinic was one year, while median age at presentation was 65 years. Our case series included the following diagnoses: cutaneous metastasis of invasive ductal carcinoma of the breast (n=2); cutaneous metastasis of colorectal adenocarcinoma (n=1); Marjolin's ulcer (n=1), basal cell carcinoma (BCC) (n=2), primary cutaneous squamous cell carcinoma (SCC) (n=1), metastatic malignant melanoma (n=1), cutaneous T-cell lymphoma (n=1), cutaneous angiosarcoma (n=1), Kaposi sarcoma (n=1) and recurrent tonsillar SCC with osteoradionecrosis (n=1); one case had both BCC and SCC. CONCLUSION: Punch and excisional biopsies were the most frequently used diagnostic techniques. Local wound therapy addressed bleeding, malodour, exudate, pain and infection. However, wound healing is usually achieved once the underlying malignancy is treated. In advanced or metastatic disease, palliative wound care aims to prevent exacerbation of existing wounds and focuses on patient comfort.

According to the latest data provided by Globocan 2020, the incidence of colorectal cancer ranks third, after lung cancer and breast cancer, becoming a more and more important global health issue. Of the cases diagnosed with colorectal cancer, more than 25% are diagnosed in the metastatic stage, with the presence of secondary tumors more frequently in the liver, lung and bone. Skin metastases from colorectal cancer are still rare today (< 4%). We want to present a rare, unique case in our department of a 74-year-old patient diagnosed 9 years ago with a malignant rectal tumor who, after a disease-free period of approximately 8 years and a half, developed multiple skin metastases of rectal adenocarcinoma.

AIMS: Cutaneous metastases of internal malignancies occur in 1-10% of cancer patients. The diagnosis can sometimes be challenging, especially in cases with an unknown primary cancer. MATERIALS AND METHODS: A retrospective case review was performed including all cases of skin metastases from primary internal malignancies diagnosed at the Department of Pathology at the Maastricht University Medical Centre+ from 2007 to 2021. The clinicopathological data were collected and immunohistochemical and molecular diagnostic tests were performed to confirm the primary origin of the metastases. RESULTS: We identified 152 cases (71 female; 31 male patients) of cutaneous metastases of internal malignancies. 28 patients (20 women and 8 men) were diagnosed with multiple cutaneous metastases. Among the female patients, the most common primary tumour was breast cancer (50% of the cases), followed by lung (13.6%), gynaecological (7.3%), and gastrointestinal origin (7.3%). Among the male patients, the most common primary sites were gastrointestinal and lung origin (altogether, 50% of the cases). In 19 patients, the cutaneous metastasis was the first presentation of a clinically silent internal malignancy (18.6%), of which most (78.9%) represented metastatic lung carcinomas. Finally, metastasizing patterns were different across tumour types and gender. CONCLUSION: Breast, lung, gastrointestinal, and gynaecologic cancers are the most common primary tumours demonstrating skin metastases. Infrequently, cutaneous metastases can be the first clinically visual manifestation of an underlying not yet diagnosed internal malignancy; therefore, occasional broad immunohistochemical profiling, molecular clonal analysis, and a continuous high level of awareness are necessary for a precise diagnosis of cutaneous metastases of internal malignancies.

B-cell lymphoma of the central nervous system (CNS) is a rare malignancy with diffuse large B-cell lymphoma (DLBCL) variant being most common. Although DLBCL has a high propensity to relapse locally within the CNS, only a few cases of cutaneous metastasis have been described in the literature. We present a unique case of cutaneous metastasis of a primary DLBCL of the CNS in a 79-year-old man who was in clinical remission for 4 years until presenting with a lesion in the left adrenal gland and cutaneous nodules on the left flank. Skin biopsy specimen revealed a diffuse dermal infiltrate of atypical B-cell lymphocytes with expression of CD20, BCL-2, BCL-6, and MUM-1, suggestive of DLBCL. For differentiation between another primary or a recurrent process, immunoglobulin kappa (IgK) light chain gene rearrangement was performed and demonstrated that the DLBCL of the skin and CNS were of the same clonal origin. Restaging computerized tomography after initiating chemotherapy and daily ibrutinib showed complete resolution of the left adrenal mass and resolving cutaneous lesions. Our case demonstrates the rare, late cutaneous metastasis of DLBCL of the CNS and highlights the importance of genetic testing for the distinction between the primary and secondary lesions.

Introduction: Metastatic disease can be observed in nearly 25% of all renal cell carcinoma cases (RCC). This can present in the skin as a late symptom of the disease or as a manifestation of an undetected, asymptomatic RCC. Aim: To review the literature and present a case study of cutaneous metastasis in primary genitourinary malignancy, especially RCC in order to broaden the related knowledge. Material and methods: The first stage of our work was focused on presenting the results of the literature review about cutaneous metastasis in the patients with renal cell carcinoma. Next, taking into account that this type of metastasis associated with RCC is relatively rare, we have decided to present a patient aged 68 with incidentally detected skin metastases of RCC located on the scalp. Results: It was diagnosed as a primary manifestation of advanced disease. Computed tomography scans showed a solid mass in the left kidney. Following surgical excision of the skin lesion, a left-side nephrectomy was performed. Conclusions: Cutaneous metastases of RCC present an unfavourable prognosis, however, remission is possible subsequent to early diagnosis and appropriate surgical excision.
RESUMO
Cutaneous apocrine carcinomas share common features with their counterparts in the breast; hence, metastatic mammary carcinoma must be excluded before such lesions can be designated primary cutaneous neoplasms. Primary tumors from either source rarely exhibit neuroendocrine differentiation. We report a case of a 72-year-old female with a painless 1.2-cm scalp nodule. An incisional biopsy revealed dermal involvement by an invasive apocrine carcinoma juxtaposed to a benign apocrine cystic lesion. Immunohistochemically, the carcinoma expressed neuroendocrine proteins including synaptophysin, chromogranin, and CD56. A primary cutaneous apocrine carcinoma with neuroendocrine differentiation was favored, but additional investigations to exclude breast origin were recommended. These revealed a 1.1-cm nodule in the right breast, which proved to be an invasive ductal carcinoma, morphologically and immunophenotypically similar to the scalp lesion. This confounded the case, yet factors militating against metastatic breast carcinoma to skin included (a) the small size of the mammary tumor, (b) absence of other metastatic disease, and (c) juxtaposition of the scalp carcinoma to a putative benign precursor. Molecular studies were undertaken to resolve the diagnostic quandary. Single nucleotide polymorphism microarray analysis revealed distinct patterns of chromosomal copy number alterations in the two tumors, supporting the concept of synchronous and unusual primary neoplasms.

Cutaneous metastasis of gastric cancer is extremely rare. Nodular forms are more common and inflammatory forms are exceptionally encountered. Herein, we report a case of inflammatory cutaneous metastasis of signet-ring cell gastric cancer (poorly cohesive gastric carcinoma with signet-ring cell component) masquerading as livedo reticularis. To our knowledge, such a clinical presentation of cutaneous metastasis has not been reported for gastric cancer. It is imperative to preserve a high index of clinical suspicion for diagnosing cutaneous metastases. Our case highlights the importance of obtaining a skin biopsy in patients with a known history of internal malignancy. Bizarre, newly erupting, evolving, persistent, or treatment-refractory dermatologic lesions (such as nodules, ulcers, erythematous, reticular, or livedoid patches) might be clues for an underlying internal malignancy and require prompt histopathological sampling. Personal medical history, histopathological examination, and immunohistochemical profiling are equally important in distinguishing primary cutaneous carcinomas from secondary metastatic deposits. Early recognition of a cutaneous metastasis might enable appropriate staging and timely intervention, thereby prolonging survival.

Palbociclib is a cyclin-dependent kinase (CDK) 4/6 inhibitor. Palbociclib combined with endocrine therapy has shown promising results in hormone-receptor-positive (HR+) and human epidermal growth factor receptor-negative (HER-2-) breast cancer progression. We present a case of a woman with a history of infiltrating lobular cancer of the left breast, status post modified radical mastectomy 6 years prior, presenting with nodular erythematous lesions on the left arm and back. Histopathological examination confirmed the diagnosis of recurrent metastatic breast adenocarcinoma. She had complete resolution of cutaneous metastasis with 1 cycle of Palbociclib. We believe our case is unique as the resolution of cutaneous metastasis with 1 cycle of single-agent Palbociclib is rare. Furthermore, it highlights the importance of considering cutaneous metastasis as a possibility in patients with prior history of primary internal malignancy.
RESUMO
Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms which account for less than 1% of all gastrointestinal malignancies. Of all the extra-abdominal metastases of GIST, superficial soft tissue metastases are the rarest. Previous reports have found success with sunitinib in imatinib-resistant GIST, but we report a certain wild-type KIT mutation GIST with cutaneous and subcutaneous metastasis that was unresponsive to multiple tyrosine kinase inhibitor (TKI) treatments. This case illustrates that knowing the specific type of KIT mutations may uncover resistance of certain GIST's to TKIs, necessitating more targeted and alternative therapy.

Cutaneous metastases from hepatocellular carcinoma (HCC) are extremely rare and can represent a sign of an underlying malignancy or relapse/progression from an existing tumor. We report a case of a cutaneous metastasis arising in a patient with metastatic HCC following orthotopic liver transplantation. Diagnosis is a multistep process as cutaneous HCC metastases must be differentiated from primary cutaneous malignancies as well as other cutaneous metastases. Making this even more challenging, HCC metastases have heterogeneous clinical and histologic appearances. Therefore, the use of immunohistochemical stains, including hepatocyte paraffin-1, arginase-1, and glypican-3, and correlation with the clinical context are essential for a correct diagnosis.

INTRODUCTION: Oral cavity malignancies constitute 30% of head and neck cancers. The most common distant metastatic sites of glottic carcinoma are usually lung, liver and bone. Although the cutaneous metastasis of head and cancers have been reported with an incidence of 0.7-2.4%, skin metastasis of glottic carcinoma is extremely rare. CASE REPORT: A 69-year-old male patient was admitted to the emergency department with hemoptysis, dyspnea, weakness in lower extremities and difficulty in swallowing. There were subcutaneous lesions with a diameter of 2-5 cm in the scalp, posterior chest wall, nose and abdomen. In addition, there was an ulcerating, painful mass on the right lateral part of the tongue. The biopsy of lesions on tongue and skin revealed a glottic squamous cell carcinoma with cutaneous metastasis.Management and outcome: The patient was treated with cisplatin 50 mg/m2 on day 1, cetuximab 500 mg/m2 on day 1 and 5-fluorouracil 1000 mg/m2 daily on days 1 and 2, repeated every two weeks. After the first cycle of chemotherapy, the lesions on the skin regressed and dysphagia improved. DISCUSSION: There are limited data about the incidence, diagnostic measures and treatment modalities of glottic cancer with cutaneous metastasis. Our case could provide an important experience to literature by its atypical presentation and treatment-sensitive nature.

Cutaneous metastases from cervix cancer are rarely described, and can appear years after a complete remission of the cancer. They may have multiple presentation as nodules, papules or telangiectasies. Unfortunately, these are associated with poor prognosis. We here report the case of a woman who developed cutaneous metastasis in the situation of a cervix cancer that appears to be stable under bevacizumab.
Les métastases cutanées provenant du cancer du col de l'utérus sont rarement décrites, et peuvent apparaître plusieurs années après une rémission complète du cancer. Elles peuvent avoir plusieurs types de présentations telles que : nodules, papules, télangiectasies. Malheureusement, ces dernières sont associées à un mauvais pronostic. Nous rapportons le cas d'une patiente qui a développé des métastases cutanées alors que son cancer primitif était stable sous traitement par bévacizumab.

BACKGROUND: Dissemination of lung cancer to cutaneous sites usually results in a poor prognosis. Pulmonary lymphoepithelioma-like carcinoma (PLELC) is a rare tumor, and no therapeutic strategy for it has yet been established. We present herein an extremely rare case of a long-term surviving patient with PLELC showing subcutaneous metastasis. CASE PRESENTATION: A 76-year-old woman was diagnosed unexpectedly as having PLELC based on a nodule on her back. After surgical resection of the primary and metastatic lesions, she has remained alive with no recurrence for over 5 years without any additional therapy. CONCLUSION: Even in the case of PLELC with subcutaneous metastasis, surgical management may afford a prognosis of long-term survival.

Cutaneous metastases from internal malignancies are uncommon. Umbilical metastasis, also known as Sister Joseph nodule (SJN), develops in patients with carcinomatous peritonitis or superficial lymphadenopathy, while non-SJN skin metastases develop after surgery, injury, and lymphadenopathy. In this review, the possible mechanisms of skin metastases are discussed. SJNs develop by the contiguous or lymphatic spread of tumor cells. After surgery and injury, tumor cells spread by direct implantation or hematogenous metastasis, and after lymphadenopathy, they spread by extranodal extension. The inflammatory response occurring during wound healing is exploited by tumor cells and facilitates tumor growth. Macrophages are crucial drivers of tumor-promoting inflammation, which is a source of survival, growth and angiogenic factors. Angiogenesis is promoted by the vascular endothelial growth factor (VEGF), which also mediates tumor-associated immunodeficiency. In the subcutaneous tissues that surround metastatic lymph nodes, adipocytes promote tumor growth. In the elderly, age-associated immunosuppression may facilitate hematogenous metastasis. Anti-VEGF therapy affects recurrence patterns but at the same time, may increase the risk of skin metastases. Immune suppression associated with inflammation may play a key role in skin metastasis development. Thus, immune therapies, including immune checkpoint inhibitors reactivating cytotoxic T-cell function and inhibiting tumor-associated macrophage function, appear promising.

BACKGROUND: Cutaneous metastases (CM) on the extremities are rare complication of cancer with poor prognosis. In general, lesions simulate an infection. Herein, we report two new cases with atypical presentation. PATIENTS AND METHODS: Case no 1: a 71-year-old man consulted for suspicion of left hand pyogenic granuloma present for 3 months. His history revealed two treated squamous-cell carcinomas (tongue and lung). On physical examination, he presented three budding and foul-smelling lesions on his left hand. Histopathology showed metastasis of squamous-cell carcinoma. Radiographic examination revealed spread of pulmonary nodules with suspicion of metastasis. Case no 2: a 68-year-old man was hospitalized for indurated edema of the right leg present for several months. Six months earlier, he had undergone surgery for left pulmonary adenocarcinoma without metastasis. Physical examination revealed an indurated edema on the right foot. Histopathology showed metastasis from adenocarcinoma. A scan revealed several osteolytic lesions in the right foot as well as lymphadenopathy. DISCUSSION: Herein, we report two original cases of CM of the extremities diagnosed as tumor progression. This is a rare complication of variable clinical presentation and impacts both cancer management and prognosis. It is important to consider the diagnosis when distal cutaneous lesions persist, particularly where there is a history of cancer.

INTRODUCTION: Cutaneous metastases are common in patients with malignant melanoma. In rare cases, they are distributed on a dermatome, in which case they are known as zosteriform metastases. OBSERVATION: We report the case of a patient with zosteriform metastasis of a malignant melanoma, progressing unfavourably despite surgical excision and immunotherapy. DISCUSSION: The physiopathology of this condition continues to be poorly understood.
