Determination of the causative agent of erythema-like skin lesions in case of nonspecific superficial perivascular dermatitis was supported by histological examination and led to the latter diagnosis of Hyperkeratosis lenticularis perstans (Flegel disease) in patient. The presence of antibodies against Borrelia burgdorferi in patient serum was confirmed by a routine ELISA method and verified by Western blot technique. Skin biopsy and blood specimens were analyzed by PCR and multilocus sequence analysis (MLSA). Read More

We report a case of a 25-year-old man, who presented with 1-5 mm multiple asymptomatic hyperkeratotic papules of 15 years duration on both legs and hand along with lichenified plaques with Koebner phenomenon in the axillary folds, anticubital and popliteal fossae.

Department of Anatomic Pathology, Hospital El Bierzo, Spain.

We present a case of hyperkeratosis lenticularis perstans (Flegel's disease) in a 71-year-old-woman. Apart from all the typical morphological features of the disease, we evidenced mounds of parakeratosis that contained neutrophils, alternating with other strata of the horny layers in which no infiltrate was seen. Such a pattern has been described in association with diseases that show a periodic clinical pattern of presentation with periods of exacerbations and remissions. Read More
