Exuberant connubial allergic contact dermatitis from diphenhydramine.

Connubial or consort allergic contact dermatitis occurs when the agent causing the dermatitis has not been used by the patient but by his partner or other cohabitants or proxy. Most cases are due to fragrances, cosmetics or topical nonsteroidal anti-inflammatory agents. We report a case of a connubial dermatitis caused by topical diphenhydramine in a woman who applied the cream on her husband's back.
