“…Primula dermatitis is mainly caused by P. obconica and has variable clinical manifestations that are often misdiagnosed, since patients usually do not present with a typical picture of plant dermatitis with blotches and linear streaks on the skin (11,(18)(19)(20)(21)(22)(23)(24). Consequently, the allergen primin has been included in the European standard series (20).…”

“…The degree of sensitivity and the intensity of exposure determine the pattern of dermatitis. The main pattern of primula dermatitis is facial dermatitis, alone or in combination with limb or hand dermatitis (3,6,11,12,(18)(19)(20)(21)(22)(23)(24). Most cases of primula dermatitis are due to direct contact with the plants, whereas only a few cases of airborne contact dermatitis have been described (3,6,12,15).…”

The allergen primin and its precursor miconidin were collected by dynamic headspace technique from Primula obconica Hance and quantified and identified by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The primin concentrations in leaves/stems and flowers (including pedicel and calyx) of P. obconica were 262 microg and 531 microg (g fresh plant material)(-1), respectively, whereas miconidin concentrations were 92 microg (g fresh plant material)(-1) in leaves/stems and 194 microg (g fresh plant material)(-1) in flowers. The amounts of primin released from unchopped leaves/stems and flowers were 65.3 ng and 18.8 ng (g fresh plant material)(-1) h(-1), respectively. Dynamic headspace analysis of intact P. obconica plants showed that primin is also directly emitted from undamaged plants, although in smaller concentrations (6.2 ng (g fresh plant material)(-1) h(-1)), whereas miconidin was only emitted in minute amounts (less than 0.4 ng (g fresh plant material)(-1) h(-1)) both from intact plants and from unchopped plant parts. The possibility that primin from P. obconica could be a potential airborne allergen and therefore a source of airborne contact dermatitis is discussed.

A case of the hands and face dermatitis in a patient employed in a store with motor-car spare parts is presented. Both the patient and her doctor were convinced that skin lesions were caused by the contact with metals, oils and greases. After detecting allergy to primine (after 48 and 96 h, ++), the patient recalled that two months earlier she had started to grow primrose (Primula obconica) at home. Patch tests with the primrose leaf and flower were also positive (++). The presented case provides evidence that routine primine testing is essential in all patients with suspected contact allergy dermatitis. In Poland like in the majority of countries, primina is not included in the standard kit. CASE REPORTA 52-year-old woman without history of atopy employed in a shop with motor car spare parts for 15 years consulted a physician in the Department of Occupational Diseases. Three months earlier she developed hand dermatitis, affecting particularly the fingers (erythema, vesicles) and erythema with edema on the eyelids and cheeks (Figs. 1 and 2). The patient and her doctor were convinced that the dermal changes were due to contact with metals, lubricants or greases at her workplace. Therefore, she was
