1/6. Tufted hair folliculitis: a pattern of scarring alopecia?We present a patient with pemphigus vulgaris who, over the years, experienced the development of tufted hair folliculitis as a result of scalp involvement. Multiple hairs emerged from widely dilated follicular ostia surrounded by indurated, scarred skin. Histopathologic findings were typical for tufted hair folliculitis. We believe that because a specific host response to scalp injury might be crucial to the development of this rare disorder, it should be regarded as a type of scarring alopecia.- - - - - - - - - - ranking = 1keywords = vulgaris (Clic here for more details about this article) |
2/6. Tufted hair folliculitis associated with pemphigus vulgaris.Tufted hair folliculitis (THF) is a rare disease which is characterized by the emergence of multiple hairs from widely dilated follicular orifices surrounded by an inflammatory infiltrate resulting in scarring alopecia. The pathogenesis is not yet fully understood. Although colonization with staphylococcus aureus could not always be detected and systemic treatment with antibiotics alone is not sufficient, this microorganism is considered to play an important role. Around 30 patients with THF have been reported since the first publication. We present a patient with pemphigus vulgaris who developed THF. To our knowledge, this is the fourth case with an association of these two entities. Amongst other causing mechanisms, the autoimmune reaction may play an important role for the development of THF.- - - - - - - - - - ranking = 5keywords = vulgaris (Clic here for more details about this article) |
3/6. pseudomonas aeruginosa gram-negative folliculitis.Three patients with sudden, unmanageable exacerbation of acne vulgaris were shown to have Gram-negative folliculitis due to pseudomonas aeruginosa. In each patient, the source of the Pseudomonas proved to be an otitis externa infection. In contrast to previous cases of Gram-negative folliculitis due to proteus, escherichia coli, or klebsiella, the anterior nares were not colonized. Treatment of the otitis externa and the Gram-negative folliculitis with acetic acid compresses and topical antibiotics led to prompt resolution without recurrence.- - - - - - - - - - ranking = 1keywords = vulgaris (Clic here for more details about this article) |
4/6. Disseminated lupus vulgaris presenting as granulomatous folliculitis.A 69-year-old man presented with a 3-year history of scattered, grouped, asymptomatic follicular papules, pustules, and nodules tending toward coalescence into large geographic aggregates. Repeated cutaneous biopsy specimens showed granulomatous folliculitis with negative Ziehl-Neelsen stains. Finally, biopsy material submitted for mycobacterial culture grew mycobacterium tuberculosis. No evidence of active systemic tuberculosis was found. The patient had a very rare form of tuberculosis, disseminated lupus vulgaris, presenting with granulomatous folliculitis, which is usually not seen in lupus vulgaris. The lesions resolved after an 18-month course of isoniazid and rifampin. The unusual clinical and histologic presentation as well as occasional partial remissions following a variety of nonspecific empiric therapies delayed diagnosis despite multiple evaluations. This case illustrates the importance of obtaining mycobacterial cultures from skin biopsy specimens in addition to special stains whenever cutaneous tuberculosis is suspected.- - - - - - - - - - ranking = 6keywords = vulgaris (Clic here for more details about this article) |
5/6. skin infection provoked by coagulase-negative Staphylococcus resembling gram-negative folliculitis.A superficial pustular eruption with acute onset has been reported in patients with acne vulgaris receiving systemic antibiotic treatment. In all past cases the causative micro-organism was found to be a gram-negative bacterium. This case report describes a similar clinical picture under the same circumstances, in which the bacterium incriminated was a coagulase-negative Staphylococcus.- - - - - - - - - - ranking = 1keywords = vulgaris (Clic here for more details about this article) |
6/6. Tufted hair folliculitis developing in a recalcitrant lesion of pemphigus vulgaris.We describe tufted hair folliculitis that developed in a chronically erosive plaque on the scalp of a Japanese man patient with pemphigus vulgaris. After repeated intralesional corticosteroid injections, the erosive lesion improved, leaving multiple hairs emerging from single follicular openings. The current case suggests that localized exudative inflammatory lesions in the scalp regardless of cause can result in tufted hair formation.- - - - - - - - - - ranking = 5keywords = vulgaris (Clic here for more details about this article) |
