A Rare Case of Male Breast Cancer Presenting as a Superficial Pigmented Nipple Tumor: The Importance of a Deep Excisional Biopsy and Immunohistochemical Analysis in Diagnosis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Nipple lesions present diagnostic challenges due to overlapping clinical and histopathological features. A 65-year-old male presented with a black skin lesion on his right nipple, initially suspected to be malignant melanoma. Dermoscopy suggested basal cell carcinoma, while punch biopsy findings indicated sweat gland carcinoma with negative mammaglobin staining. However, total resection revealed cord-like invasion into the deep dermis near the mammary gland, and immunohistochemistry showed mammaglobin positivity, leading to a final diagnosis of solid-type invasive ductal carcinoma of the breast. This case highlights the diagnostic challenges of male nipple tumors and underscores the need for thorough histopathological and deep-layer assessment to distinguish breast cancer from cutaneous malignancies.
