Cutaneous metastases from urothelial carcinoma of the bladder are a rare disease. In previous reports, the most common metastatic cutaneous lesions were non-tender nodules on the abdominal skin. We report a patient with bladder urothelial carcinoma with cutaneous metastases initially presenting as right leg and suprapubic lymphedema. Bladder tumor was the incidental finding by magnetic resonance venography. Urothelial carcinoma (clinical stage IV) was diagnosed, and chemotherapy was performed. Extensive painful erythematous plaques with an erysipelas-like appearance located on the suprapubic area, chest and abdomen were noted, and cutaneous metastases were confirmed by histopathology. Subsequently, extensive scrotal and prepuce ulcerative changes developed. This paper reports a rare case of extensive cutaneous metastasis of bladder urothelial carcinoma who presented an interesting clinical course.

Cutaneous metastases can have many different clinical presentations. They are seen in patients with advanced malignant disease; however, they can be the initial manifestation of undetected malignancies. Inflammatory breast carcinoma is a rare and aggressive form of breast cancer that has a nonspecific appearance mimicking many benign conditions including mastitis, breast abscesses, and/or dermatitis. The authors report the case of a 40-year-old woman with inflammatory breast carcinoma presenting with violaceous papulovesicular lesions resembling lymphangioma circumscriptum and erythematous patches resembling erysipelas. These lesions represent two different types of cutaneous metastases, both of which were the initial signs of inflammatory breast carcinoma in the patient described herein. Skin biopsy of lesions confirmed invasive breast cancer and further prompted a work up for inflammatory breast carcinoma. This case demonstrates the importance of follow-up for all breast lesions, even those considered to be of benign nature, for they can be presenting signs of metastatic breast cancer.

From a clinical point of view, the most common presentations of cutaneous metastatic disease are papules and nodules. However, a wide morphological spectrum of lesions has been described, including erythematous patches or plaques, inflammatory erysipelas-like lesions, diffuse sclerodermiform lesions with induration of the skin, telangiectatic papulovesicles, purpuric plaques mimicking vasculitis, and alopecia areata like scalp lesions. The so-called zosteriform pattern has been described to be in few cases and to the best of our knowledge has never been described associated with a metastasis of a nasopharyngeal carcinoma. This case highlights the relevance of including cutaneous metastases in the differential diagnosis of patients with nonhealing herpes zoster-like lesions, especially in those with underlying neoplasm recently diagnosed.

Cutaneous metastases of the breast carcinomas can present clinically as nodules, plaques and tumors (most commonly as nodules) as well as 'erysipelas-like' lesions are known as 'carcinoma erysipeloides'. We want to share our experience in diagnosing a middle-aged lady with carcinoma erysipeloides secondary to breast carcinoma and her management as this is commonly misdiagnosed as cellulitis or scleroderma in general practice. Unfortunately, the patient had presented to us at a late stage with wide-spread metastasis, and as such, chemotherapy was the only available option. She expired after her third cycle of chemotherapy.

Dear Editor, Cutaneous metastases (CM) are detected in about 0.6-10.4% of patients with an internal malignancy (1-3). Excluding melanoma, breast and lung carcinomas are the main source of CM in women and men, respectively (1,4,5). CM can have different clinical features, and a diagnosis of CM is usually suspected before performing a biopsy. However, this can be a pitfall for clinicians when the clinical presentation is not the typical inflammatory nodule or mass. Herein we report 2 cases of cutaneous metastases of breast carcinoma, initially treated as a common skin infection. Case 1 A 51-year-old Caucasian woman presented to our Institute with a four-month history of diffuse and erythematous pustular, lesions on the right arm that were painless and non pruritic (Figure 1). The patient had undergone excision for a breast adenocarcinoma (stage IIIA) 5 years earlier. An initial diagnosis of folliculitis was established, and the patient started systemic and topical antibiotics without any improvement. Based on the clinical features and the patient medical history, we performed a skin biopsy. Pathologically dermal nests of tumor cells, arranged in a glandular-like pattern and involving the perifollicular and follicular areas (Figure 2, Figure 3), were highlighted. The tumor cells were positive to cytokeratin (CK) 7, CK19, and carcinoembryonic antigen (CEA) and negative for CK20, CK5/6, CD10, and thyroid transcription factor-1 (TTF-1) (Figure 4). According to the clinical history and pathology, a final diagnosis of folliculotropic metastatic breast carcinoma was established. Unfortunately, the patient died after 10 months. Case 2 A 61-year old Caucasian woman presented to our Department with a two-month history of pink/violet macular lesions with diffuse telangiectasia on the left breast and arm (Figure 5, Figure 6). Five years earlier she had undergone excision for a breast adenocarcinoma (stage II A). A previous diagnosis of cellulitis had been made, and systemic antibiotic therapy had been started without any improvement. Based on the clinical features and the patient medical history, a punch biopsy was performed. Examination of skin biopsy showed a diffuse, sclerotic, and mixoid stroma with several dense ectatic lymphatic vessels (Figure 7, Figure 8). The dermal and hypodermal lymphatic lumens were filled with neoplastic cells. Thus, a diagnosis of cutaneous lymphangitis carcinomatosa (CLC) was established. Unfortunately, the patient died after 8 months. Discussion CM are present after breast carcinoma in about 23.9% of patients, often involving the chest and abdomen and manifesting on average 5 years after surgical removal of the first malignancy (1,6). CM of breast cancer are usually solitary or multiple nodular pinkish lesions (ranging between 1 and 3 cm) (1). However, several clinical features have been reported in the literature, including telangiectatic carcinoma, erythema-like, erythema annulare centrifugum-like, morphea-like, erysipelas-like, dermatofibroma-like, herpes-zoster-like, and alopecia-like lesions (1,7-10). Clinical and pathological images of folliculitis-like metastases are rarely reported in the literature, especially after breast cancer (11,13) Clinically, folliculitis-like metastases could resemble a zosteriform-like metastatic lesion (7,14,15) although they do not follow a dermatome and are pustular lesions rather than violaceous indurate papules and/or nodules (13,14) Pathologically, our cases showed an infiltration of the dermis and pilosebaceous units growing through the pilosebaceous unit in a "pseudo-eruptive way". In this regard, folliculitis-like CM could be similar to alopecia neoplastica, where the metastatic process involves and destroys the pilosebaceous units completely, leading to scarring alopecia (9,10). However, in our case, the pilosebaceous unit was still slightly recognizable, and clinically there were no scar-like features. The mechanism of folliculitis-like metastasis formation is currently unknown. As reported in zosteriform-like metastases, the lymphatic and hematogenous spread of malignant cells or the koebnerization at the site of a previous viral and/or bacterial infection could lead to metastasis (7,14-16). However, unlike zosteriform-like metastases, the spread of neoplastic cells from the dorsal root ganglia was not a plausible mechanism of metastasization in our cases because of the absence of dermatome involvement. Furthermore, there were no signs of possible koebnerization in a previous bacterial and/or viral infection site (7,13) In our opinion, folliculitis-like metastasis may be a result of the skin extruding malignant cells through the pilosebaceous unit to limit the neopalstic proliferation. This could explain the clinical and pathological features of folliculitis-like metastasis. Alternatively, the adnexotropic behavior of malignant cells may be explained by homing mechanisms, involving the up-regulation of the intercellular adhesion molecule 1 (ICAM-1) on the follicular epithelium, such as folliculotropic mycosis fungoides (17). In our patient, the folliculitis-like eruption was the first sign of recurrence after 5 years of disease-free survival. It is evident that the unusual folliculitis-like eruption of CM led to a delay in the diagnosis. CLC is a rare presentation of skin metastasis, characterized by an occlusion of dermic lymphatic vessels by neoplastic cells (18). CLC has been reported in the literature in association with several malignancies, including lung, breast, and ovarian cancer (19). CLC shows pink/violet macular lesions with diffuse telangiectasias, often associated with itching and burning sensation. The main differential diagnoses are erysipelas and cellulitis. However, CLC is not associated with fever, chills, and leukocytosis. Furthermore, CLC shows no response to antibiotic therapies. Several clinicopathological types of cutaneous metastasis have been reported in the literature, including telangiectatic metastatic breast carcinoma (TMBC) and carcinoma erysipelatous (CE). TMBC is characterized by yellowish/reddish or violaceous papulo-vesicular lesions. CE usually shows blistering erythematous eruptions resembling erysipelas. However, CLC, TMBC, and CE are different clinical expressions of the same metastatic process, pathologically characterized by edema of the dermis and ectatic lymphatic vessels. Positivity to CD31 and podoplanin in the endothelial cells shows that the tumor metastatises predominantly via lymphatic vessels (20). In conclusion, we stress that every cutaneous lesion should be studied and examined carefully in patients with a personal history of cancer. Indeed, a correct diagnosis remains the pivotal point for a better management of these patients.
