Perforating cutaneous metastasis from an ovarian adenocarcinoma

Perforating Fibrous Histiocytoma Mimicking Keratoacanthoma: A Case Report

A 31-year-old male presented with a firm, well-demarcated, erythematous, crateriform, and ulcerated nodule in the left lumbar region, which persisted for 3 months. Clinically, a keratoacanthoma was suspected. The histological analysis was consistent with perforating fibrous histiocytoma, a rare histopathologic variant of fibrous histiocytoma. To our knowledge, this is the third case reported in the literature.

Cutaneous Ovarian Carcinoma Metastases: Case Report and Literature Review

Metastatic cutaneous ovarian carcinoma is a rare diagnosis with a poor prognosis. Cutaneous manifestations are variable in size and morphology. We report a woman presenting with cutaneous ovarian metastases mimicking reticulated dermatoses. Our patient presented with a four-month history of a mildly pruritic eruption in the setting of stage IV ovarian adenocarcinoma, for which she was undergoing carboplatin, doxorubicin, and bevacizumab chemotherapy. On exam, she had erythematous, indurated papules and plaques involving the right flank and breast, as well as a reticulated erythematous patch on the lower abdomen. Cutaneous ovarian metastases have varied presentations. Our case highlights an uncommon manifestation of ovarian metastases and reviews the prior literature.

Ovarian carcinoma presenting as cutaneous nasal metastasis

Metastatic ovarian cancer uncommonly presents with skin metastasis. When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala. A skin biopsy was performed and histopathological and immunohistochemical findings were compatible with a cutaneous metastasis of adenocarcinoma. A systematic investigation revealed a bilateral ovarian cystadenocarcinoma associated with visceral dissemination, likely associated with nose cutaneous metastasis. We report a very uncommon case because of the presentation of ovarian carcinoma as cutaneous metastasis. To our knowledge, this atypical localization on the nose has not been described yet in the literature.

MUCI positive cutaneous metastasis with transepidermal elimination from a breast carcinoma

Breast cancer is the most common cause of cutaneous metastases from internal malignancies. Generally, the neoplastic cells are located in the dermis or hypodermis, while a finding of transepidermal elimination on cutaneous metastases is exceptional. In this report we present a patient with perforating cutaneous metastases from breast cancer with mucin 1 expression. Cutaneous, bone, lung, and hepatic lesions were detected two years after the diagnosis of the primary tumor.

Cutaneous metastasis: clinicopathological study of 72 patients from a tertiary care center in Lebanon

BACKGROUND

Cutaneous metastasis is the result of malignant cell spread from primary malignancy to the skin. This is not uncommon, and rates reported in the literature are as high as 10.4%. To the best of our knowledge, there are no studies assessing the epidemiologic, clinical, and histopathological features of cutaneous metastasis in our region.

OBJECTIVE

To assess the clinical and histopathological findings of all patients diagnosed with cutaneous metastasis at the American University of Beirut - Medical Center (AUB-MC) and to compare our findings with those published in the literature.

METHODS

Retrospective clinical and histopathologic evaluation of all cases diagnosed as cutaneous metastasis at AUB-MC between 1992 and 2010.

RESULTS

A total of 72 patients (50 females and 22 males) were identified. The mean age at diagnosis was 55.2 years. The most common primary cancer was breast cancer in women and laryngeal cancer in men. The most common clinical presentation was a single nodule in 27% of cases followed by multiple nodules in 23%. Cutaneous metastasis lesions were asymptomatic in the majority. The chest was the most commonly affected site. On microscopy, the majority of metastatic cases were adenocarcinomas (74%).

CONCLUSION

This is, to our knowledge, the first study characterizing the epidemiological, clinical, and histopathological features of cutaneous metastasis in the Lebanese population. The clinical and histopathological features observed were in concordance with the published literature, with minor differences.
