Berloque dermatitis is a type of photocontact dermatitis. It occurs after perfumed products containing bergamot (or a psoralen) are applied to the skin followed by exposure to sunlight. Striking linear patterns of hyperpigmentation are characteristic, corresponding to local application of the scented product. Read More

Phytophotodermatitis is a phototoxic dermatitis resulting from contact with psoralen-containing plants such as celery, limes, parsley, figs, and carrots. Berloque dermatitis is a variant of phytophotodermatitis and is caused by high concentrations of psoralen-containing fragrances, most commonly oil of bergamot. Berloque dermatitis is rarely seen today because of the removal of these fragrances from most cosmetic products in the United States. Read More

Besides the inherited forms of mottled and reticulate pigmentation, a vast number of diseases and trigger mechanisms can lead to acquired pigmentation of the neck. Nonhereditary variants of reticulate and mottled pigmentation can affect the neck as a typical site and therefore may give a diagnostic clue or it can occur sporadically on the neck as well as on other sites. A well-known and important factor in the pathogenesis is exposure to sunlight. Read More

In several patients the effect of a phototoxic reaction to the juice of fresh figs (ficus carica) was observed as a striped pigmentation on the arms (after rubbing in the fruit juice followed by exposure to the sun), or as a patchy pigmentation of the face after eating fresh figs. Reference is made to the pathogenetic identity of this furocoumarin phototoxic reaction and the clinical transition of ficus dermatitis both to "Berloque dermatitis" (from the oil of types of citrus) and to bullous meadow dermatitis (from the juice of types of heracleum). Reference is also made to the similarity of the therapeutic furocoumarin reaction in PUVA therapy. Read More

Despite the decline in the incidence of berloque dermatitis during the past decade, milder cases resulting from the presence of relatively small quantities of bergapten in perfumed cosmetics continue to occur. The resultant hyperpigmentation may have an atypical presentation leading to error in diagnosis. In addition, the condition can sometimes induce or aggravate melasma and may be responsible for other pigmentary disorders of the face and neck of questionable etiology such as poikiloderma of Civatte, Riehl's melanosis and pigmented peribuccal erythema of Brocq.

Berloque is no more used in the French language, the term of now-a-days is breloque. Therefore the expression berloque-dermatitis is either an anachronism or a mix-up of two letters. Read More
