Cutaneous metastases as a primary manifestation of invasive ductal carcinoma of the breast: a case report

Introduction:Cutaneous metastases as the first sign of invasive ductal carcinoma are not common. The ambiguous presentation of asymptomatic lesions may result in various diagnoses including dermatologic causes. Early diagnosis is essential in such cases. Case presentation:A 43-year-old woman with no risk factors for developing breast cancer at a young age was diagnosed with invasive ductal carcinoma of the left breast after dermatologic complaints of diffuse lesions on the left-back and right subclavian region. The patient remained asymptomatic except for the recent cutaneous presentation, which did not arouse much suspicion. Conclusion:Cutaneous metastases of breast cancer remain uncommon, but at the same time represent a poor prognosis for the patient, and when they do occur, treatment options are limited. The delay in taking the proper diagnostic measures in such cases imposes a need to adopt a wider perspective when dealing with the possible occurrence of advanced disease. This also adds up to the importance of breast self-examination by women at a young age and full examination by physicians, especially when they encounter a misguiding presentation.
