Erythema elevatum diutinum in the setting of connective tissue disease and chronic bacterial infection.

Erythema elevatum diutinum (EED) is a rare and chronic cutaneous leukocytoclastic vasculitis. It is predominantly seen on the extensor surfaces of the extremities. Although a specific cause is largely unknown, EED has been noted to occur in association with a wide variety of diseases. A 28-year-old man with systemic lupus erythematosus (SLE) and a 53-year-old woman with an overlap syndrome of rheumatoid arthritis and polymyositis are presented. Both patients developed EED in the setting of chronic recurrent bacterial infections. Patients with a connective tissue disease are at increased risk for such infections secondary to immunosuppression, either from the disease itself or secondary to immunosuppressive therapy. EED has been independently reported to occur in the setting of connective tissue disease as well as in the setting of chronic infection. Our patients had both of these underlying conditions, which are known to predispose patients to immune complex-mediated vasculitides, in this case EED. One patient's EED responded to treatment of the SLE and the other improved, as has been previously reported with dapsone.

Cutaneous draining sinus tract of odontogenic origin: unusual presentation of a challenging diagnosis.

A 44-year-old woman presented with a chronically draining lesion on her cheek just lateral to the nasofacial sulcus. The lesion was refractory to treatment with oral antibiotics. Physical examination revealed poor dentition, and a panoramic radiograph demonstrated periapical abscesses in the maxillary right lateral incisor and canine. A diagnosis of cutaneous fistula of odontogenic origin was made, and the patient was treated with tooth extraction. The cutaneous fistula subsequently resolved. Intraoral examinations and radiographs are critical for making the diagnosis of cutaneous draining sinus tract of odontogenic origin. Many patients undergo unnecessary surgical therapies before having the correct diagnosis made, but root canal therapy or surgical extraction is the treatment of choice. A dental origin must be considered for any chronically draining sinus of the face or neck.

Relationship between age of ear piercing and keloid formation.

OBJECTIVE: Keloids occur commonly after trauma to the skin, with ear piercing being a well-known inciting event. We surveyed 32 patients with keloids resulting from ear piercing, to examine a potential relationship between age of piercing and keloid formation. METHODS: A total of 32 consecutive patients completed a survey about ear-piercing and keloid formation. Fisher's exact test was used for data analysis. RESULTS: Fifty percent (n = 16) of surveyed patients developed a keloid after their first piercing. Twenty surveyed patients developed keloids with subsequent piercings. Those who had piercings at > or =11 years of age were more likely to develop keloids (80%) than were those who had piercings at <11 years of age (23.5%). CONCLUSIONS: Keloids are more likely to develop when ears are pierced after age 11 than before age 11. This observation holds true for patients with a family history of keloids. Given the difficulty and cost of treating keloids, prevention remains the best approach. Patients with a family history of keloids should consider not having their ears pierced. If this is not an option, then piercing during early childhood, rather than later childhood, may be advisable. Primary care physicians and pediatricians should educate children and their parents about the risk of keloid formation.

Domestic violence in the outpatient setting.

Domestic abuse is a serious problem that may present directly or indirectly in the clinical setting. The astute physician may have the opportunity to directly intervene in this national dilemma. We present a patient who indirectly sought help through the medical setting, review the physician's responsibilities, and offer guidelines for management.

Paraneoplastic autoimmune multiorgan syndrome (paraneoplastic pemphigus) in a child: case report and review of the literature.

Paraneoplastic autoimmune multiorgan syndrome, also known as paraneoplastic pemphigus, has been observed only rarely among children. We describe a 10-year-old boy with typical clinical and histologic findings of paraneoplastic pemphigus associated with Castleman's disease. His disease was refractory to resection of the tumor and aggressive combination immunosuppressive therapies. The patient died 1 year after presentation, as a result of complications of bronchiolitis obliterans. This case is unusual because of the young age of the patient.

Confluent and reticulated papillomatosis: response to tazarotene.

Confluent and reticulated papillomatosis of Gougerot and Carteaud is an uncommon dermatosis of unclear cause that can be recalcitrant to therapy. We report the case of an 11-year-old black girl with the eruption in whom it completely cleared using tazarotene gel. The treatment was well-tolerated and we suggest considering topical tazarotene as an alternative to systemic retinoid therapy.

Palisaded neutrophilic granulomatous dermatitis in rheumatoid arthritis.

Palisaded neutrophilic granulomatous dermatitis (PNGD) is an entity that has not been clearly defined either clinically or histopathologically. It is seen in patients with rheumatoid arthritis and other connective tissue diseases. In the past, many cases of PNGD have been described under several different names including palisaded neutrophilic and granulomatous dermatitis, linear subcutaneous bands, interstitial granulomatous dermatitis with cutaneous cords and arthritis, rheumatoid papules, and Churg-Strauss granuloma. We report 7 additional cases of PNGD. Clinically, 6 patients presented with erythematous to violaceous plaques, papules, and nodules on multiple body sites; one presented with subcutaneous linear bands on the shoulder. Five had rheumatoid arthritis; one had adult-onset Still's disease; and one showed clinical signs of rheumatoid arthritis, although serologically the rheumatoid factor was negative. On histologic examination, a spectrum of changes was observed ranging from urticaria-like infiltrates to leukocytoclastic vasculitis and granuloma annulare with neutrophils. We report these cases to expand the histologic spectrum of this entity and to further delineate the different forms of clinical presentation.

Infantile perianal pyramidal protrusion: report of a case and review of the literature.

Infantile perianal pyramidal protrusion is an important, relatively newly recognized condition, which is thought to be under-reported in the pediatric literature. Previous reports refer to these lesions as skin tags or skin folds. More recently, the name infantile perianal pyramidal protrusion has been suggested, based on the characteristic presentation of the lesion in prepubertal children, especially girls. Recognition of these lesions has many implications regarding proper diagnosis and management. They may easily be mistaken for condyloma accuminata or as a sign of trauma, leading to an investigation of sexual abuse. This situation may be avoided with awareness of this entity in combination with thorough history taking and a classic presentation. We present a classic presentation of infantile perianal pyramidal protrusion and further discuss this condition.

Video game induced knuckle pad.

Controversy and concern surround the video game playing fascination of children. Scientific reports have explored the negative effects of video games on youth, with a growing number recognizing the actual physical implications of this activity. We offer another reason to discourage children's focus on video games: knuckle pads. A 13-year-old black boy presented with an asymptomatic, slightly hyperpigmented plaque over his right second distal interphalangeal joint. A punch biopsy specimen confirmed knuckle pad as the diagnosis, and a traumatic etiology from video game playing was suspected. Knuckle pads can be painful, cosmetically unappealing, and refractory to treatment. They can now be recognized as yet another potential adverse consequence of chronic video game playing.
