Cyclophosphamide, an alkylating agent, has rarely been observed to cause a bluish discoloration of nails, an occurrence that is typically underreported. We describe the case of a middle-aged male undergoing dexamethasone-cyclophosphamide pulse therapy for pemphigus foliaceus, who exhibited bluish-gray discoloration of the nails. It is crucial to differentiate this presentation from other conditions such as nail apparatus melanoma (NAM), which may manifest in a slightly different manner. We also report the onychoscopic findings observed in this case.

Colloidal silver used as a suspension for (alternative) therapeutic purposes or silver exposure due to environmental or working conditions can lead to irreversible deposits of silver granules in the skin (bluish-gray hue of the skin), mucosa, cornea, retina and internal organs. Silver-induced discoloration of the conjunctiva should therefore be taken into account when a bluish-gray discoloration raises the suspicion of conjunctival melanoma.

Although rare, a slate gray discoloration of sun-exposed skin may occur in patients taking this medication. We present the case of a 63-year-old woman who had been taking imipramine for depression for more than 20 years when she developed a bluish gray discoloration on the face and neck that was diagnosed as imipramine-induced hyperpigmentation based on histopathology and clinical history.
