CASE REPORTS Case 1 A 23-year-old female patient was seen in the Derma- tology Department for small pustules (pin-sized), witho- ut a rash, distributed on the lateral aspects of the face, observed 2 days prior to admission (Fig. 1). She was in a good state of health, with no history of dermatological diseases, and no history of drug intake. She was a stu- dent, not working with irritants or oily substances. Usual laboratory investigations revealed no ab- normal values. Direct mycological examination and culture for fungi were negative and culture from a pustule failed repeatedly to isolate any bacteria. Swabs taken from the nose and oral cavity were ste- rile. Endocrinological examination was normal. fever or other signs of infectious disease before the eruption. At clinical examination pin-sized pustules distributed in clusters, non-flaccid, non-tender, with no signs of inflammation were seen at the margins of the lips and on the menton. A few similar pustules were present on the lips too. No adenopathy, no fever, and no other dermatological lesions were observed. Results of complete blood count with differential leucocyte count were unremarkable. Gram stain of blister fluid was negative. Analysis of blister fluid with 10% potassium hydroxide preparation showed no fungal elements. The Tzanck test was negative. HIV and VDRL tests were negative. Full blood co- unt, coagulation screen, serum chemistry and liver function tests were all within normal limits. DISCUSSION A 17-year-old man, a pupil, came to the Dermato- logy Unit due to sudden onset of a peculiar eruption around the mouth: small pustules with no erythema- tous base, non-follicular and non-pruritic (Fig. 2). He was otherwise a healthy person, with no chronic dise- ases and no previous treatments. The patient denied All pustules in patients were parafollicular. Pre- viously, they did not use cosmetics with heavy oil as make-up. There are many similarities between the cases: young persons during educational period (a student and a pupil); healthy people, no history of drug intake; pin-sized pustules arranged in a pe- culiar form on the face, which disappeared sponta- neously within one week precisely; bacteriological, mycological and virological tests were negative.
