Overview: Dermatophytic folliculitis typically presents with follicular pustules on the surface of a red, firm, exudative, and extending plaque. It can develop in association with tinea barbae, tinea capitis, or tinea corporis. Lesions of folliculitis in tinea barbae involve the beard or mustache area. Trichophytic (Majocchi) granuloma classically occurs in women shaving their legs or when tinea corporis is first treated with topical corticosteroids. Malassezia (Pityrosporum) folliculitis commonly affects young males and presents with follicular papules and pustules involving the trunk, shoulders, neck, or extensor aspects of the arms. Candidal folliculitis appears as satellite pustules around the flexural lesions of candidiasis, especially in diabetics.

Most cases of Pityrosporum folliculitis respond well to topical imidazole treatment. However, patients with extensive lesions often require oral treatment with ketoconazole or itraconazole. Once again, prophylactic treatment once or twice a week is mandatory to prevent relapse, which is unfortunately common.

Pityrosporum folliculitis is another well recognized clinical entity not infrequently found in the geriatric population. Previously referred to as ‘follicular seborrheide’6, Pityrosporum folliculitis is a chronic papulopustular eruption that is more pruritic than tinea versicolor. Sites of predilection for this clinical variant include the chest, upper back and, less frequently, the proximal extremities, face, scalp and sometimes the abdomen. This clinical entity may also be found in association with typical tinea versicolor or seborrheic dermatitis17. The primary lesions are 1 to 3 mm follicular and perifollicular erythematous papules and/or pustules. KOH preparation, culture on appropriate medium and, occasionally, a biopsy are required to distinguish this entity from bacterial folliculitides or folliculitis caused by Candida species. Predisposing factors to Pityrosporum folliculitis include diabetes mellitus and prior corticosteroid and/or antibiotic treatment. Treatment for this clinical sub-type of Pityrosporum infection includes selenium sulfide shampoo, 50% propylene glycol in water, topical econazole or ketoconazole cream and, more recently, systemic treatments with ketoconazole, itraconazole or fluconazole11,12. Responses vary considerably and the disease often recurs.
Colony stimulating factors for prophylaxis of chemotherapy-induced neutropenia in children

In 2009 study, pegfilgrastim group had about half the number of documented infections compared to filgrastim group. There wasn’t a pattern in identified pathogens between the two groups except the fact that both groups had Enterobacter sp. urinary tract infection. Pegfilgrastim arm had 4 episodes of infections with S. aureus bacteremia, S. aureus skin infection, P. jiroveci pneumonia, and Enterobacter sp. urinary tract infection. Whereas the filgrastim arm had 8 documented infections which included E. coli bacteremia, S. epidermitis bacteremia, mucocutaneous candidiasis, group A streptococcal pharyngitis, and Enterobacter sp. urinary tract infection, and pityrosporum folliculitis. In summary, pegfilgrastim showed less occurrence of documented infections in children with sarcomas [35].
