(12) In general, eight specific clinical patterns associated with cutaneous breast cancer are known: cancer en cuirasse
, inflammatory metastatic carcinoma (carcinoma erysipelatodes), (1,13) carcinoma teleangiectaticum, (14) alopecia neoplastica, (15,16) Paget's disease, (17,18) breast carcinoma of the inframammary crease, (19) metastatic mammary carcinoma of the eyelid with histiocytoid histology, (20) nodular metastases, (21,22) and mucinous adenocarcinoma metastatic to the skin (1).
We report a typical case of cancer en cuirasse in a 36 years old female who presented with diffuse erythema and scaly nodular lesions over the left breast axilla neck and arm.
Cancer en cuirasse is a rare cutaneous manifestation of breast cancer.
This term was coined by Alfred Velpeau a well-known French anatomist and surgeon after describing this condition for the first time in 1838.3 In females breast is the commonest primary source of cutaneous metastases and about 23.9% of breast cancer patients have been reported in literature to manifest cutaneous metastasis.4 These cutaneous metastases can occur in form of nodules and/or papules or telangiectatic lesions in more than 90% cases and cancer en cuirasse accounts for only about 2-3 % of such lesions.2
Cancer en cuirasse most commonly appears as a local recurrence after a few months or years of mastectomy for breast cancer.
Cancer en cuirasse develops continuitatem by dissemination via lymphogenous and 8 hematogenous pathways.
