Adverse drug reactions on the skin
Robert A. Norman in Geriatric Dermatology, 2020
Bullous and vesicular drug eruptions are diseases in which blisters and vesicles occur as a complication of the administration of drugs. Blisters are a well-known manifestation of cutaneous reactions to drugs. In many types of drug reaction bullae and vesicles may be found in addition to other manifestations. Bullae are usually noted in erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, fixed eruptions when very intense, urticaria, vasculitis, porphyria cutanea tarda and phototoxic reactions (from furosemide and nalidixic acid). Tense, thick-walled bullae can be seen in bromoderma and iododerma as well as in barbiturate overdosage.
Infections and infestations affecting the nail
Eckart Haneke in Histopathology of the NailOnychopathology, 2017
As long as the fungal spores are not seen, many other conditions, in particular other deep mycoses, tuberculosis cutis verrucosa, late syphilis, squamous cell carcinoma, or bromoderma and iododerma have to be differentiated. Cryptococcus neoformans has a mucin capsule staining with mucicarmine. B. dermatitidis has broad-based buds giving it the appearance of a shoe sole in contrast to the narrow based budding of H. capsulatum. Verrucous tuberculosis has no fungal elements. Squamous cell carcinoma and the flat form of keratoacanthoma can usually be distinguished as they do not show a mixed infiltrate with giant cells.
Descriptions of important reactions
Jerome Z. Litt, Neil H. Shear in Litt's Drug Eruption & Reaction Manual, 2017
In many types of drug reactions, bullae and vesicles may be found in addition to other manifestations. Bullae are usually noted in: erythema multiforme; Stevens–Johnson syndrome; toxic epidermal necrolysis; fixed eruptions when very intense; urticaria; vasculitis; porphyria cutanea tarda; and phototoxic reactions (from furosemide and nalidixic acid). Tense, thick-walled bullae can be seen in bromoderma and iododerma as well as in barbiturate overdosage.

Since DXM can be found in the form of a bromide salt, bromide poisoning may occur if large quantities are taken. Bromide poisoning, known as bromism, is primarily a chronic neuropsychiatric disorder manifested by behavior changes, headaches, apathy, irritation, slurred speech, psychosis, tremors, ataxia, hallucinations, and coma (James et al. 1997; Frances et al. 2003; Hsieh et al. 2007). It can also cause weight loss and bromoderma characterized as an acneiform rash mimicking a pyoderma gangrenosum (Kunze 1976; Battin and Varkey 1982; Hung 2003; Maffeis et al. 2008; Oda et al. 2016).
