A case of respiratory muscle weakness due to cytochrome c oxidase enzyme deficiency

BACKGROUND: Cytologic evaluation of abnormal nipple secretion is a well-established method for the rapid diagnosis of breast carcinoma in females. However, less attention has been focused on male patients presenting with nipple discharge. CASE: A case of intraductal carcinoma of the male breast was diagnosed by nipple discharge cytology alone. CONCLUSION: This report illustrates the usefulness of nipple discharge cytology in the diagnosis of early breast carcinoma in males.
