A Case of Infantile Digital Fibromatosis with Spontaneous Regression

We reported a fourteen-month-old boy with infantile digital fibromatosis. At the age of seven months, a nodule appeared on the back of the left third toe, and developed into a slight red tumor divided into five hemispherical nodules. Histopathologically, spindle-shaped tumor cells with an eosinophilic inclusion body in the cytoplasm were seen in the dermis. Electron microscopy showed a dense body in the cytoplasm of the tumor cells. One year and two months after the first visit, the tumor regressed without any aggressive treatment. Japanese cases of infantile digital fibromatosis were reviewed. The literature review and our case suggest that the tumor should be observed without any aggressive treatment unless it causes mobile dysfunction of the affected finger or toe.     

Infantile Digital Fibromatosis: Ultrastructural Human Papillomavirus and Herpes Simplex Virus DNA Observation

We studied a case of infantile digital fibromatosis (IDF) by transmission electron microscopy. We could not detect either human papillomavirus (HPV) DNA types 6, 11, 16, and 18, or herpes simplex virus (HSV) DNA types 1 and 2 in IDF. Our results suggest that IDF is not associated with HPV and HSV infection.     

慢性家族性良性天疱疮误诊为慢性湿疹1例

患者女,62岁。躯干、四肢皮肤皱褶处红斑、丘疹、斑块伴瘙痒20余年。先后在多家医院均按慢性湿疹治疗,无明显疗效。皮损组织病理示:表皮灶状角化不全,棘层增生肥厚,可见灶状角化不良细胞和轻度的棘刺松解现象。真皮血管周围灶状炎症细胞浸润。诊断:慢性家族性良性天疱疮。     

Infantile Systemic Hyalinosis in a Black Infant

Abstract: A black girl was born with flexion contractures and experlenced pain on movement by 1 week of age. She subsequently developed perioral papules, gingival hyperplasla, perianal nodules, torticollis, dlarhea, rectal prolapse, and inability to open her mouth. Her skin became increasingly sclerodermatous, and velvety, hyperpigmented plaques arose over bony prominences. A skin biopsy specimen snowed hyallne material in the papillary dermis with tack of elastic fibers. Ultrastructural examination revealed fibrilIogranular material around fibroblasts and blood vessels, This child had the clinical, histologic, and ultrastructural features of Infantile systemic hyalinosis. This disorder has not been described in a black infant. Previous case reports of infantile systemic hyalinosis are reviewed and unusual features of our case are discussed.     

Congenital Myofibroma Masquerading as an Ulcerated Infantile Hemangioma in a Neonate

Abstract: We report a case of a solitary infantile myofibroma masquerading as an ulcerated infantile hemangioma. Infantile myofibroma is a rare soft tissue tumor that has a good prognosis in the solitary form. It may be difficult to distinguish clinically from more common tumors of infancy such as an infantile hemangioma or from other rare entities and therefore requires a biopsy for definitive diagnosis.     

Breast Hypoplasia as a Complication of an Untreated Infantile Hemangioma

We report the case of a mixed infantile hemangioma (IH) involving the right breast that resulted in pronounced hypoplasia of the affected breast, which became apparent after breast development at puberty. No treatment had been performed in infancy or childhood. This case demonstrates that the presence of an IH may affect development of the mammary gland bud and that systemic therapy should be considered in an attempt to minimize this adverse sequela.     

Cutaneous Leishmaniasis in an Infant

Abstract: Cutaneous leishmaniasis (CL) in the United States is unusual. We report an infant who developed CL after returning from an endemic area. A skin biopsy yielded Leishmania organisms within 48 hours. The cutaneous lesions resolved with scarring after several months.     

Vegetant bromoderma in an Infant

Bromoderma is a cutaneous reaction caused by the use of products containing bromide. In this report we describe a 2-month-old girl who was admitted to our institution with vegetative lesions on the face and scalp owing to the administration of a syrup containing sodium bromide.     

Sweet Syndrome as the Presenting Manifestation of Chronic Granulomatous Disease in an Infant

Abstract: A 2.5-month-old infant had Sweet syndrome. Chronic granulomatous disease was subsequently diagnosed by the nitroblue tetrazolium reduction test. To date, this infant is the youngest reported with Sweet syndrome. Moreover, the association of chronic granulomatous disease with this syndrome has not been previously described. The precise relationship between the conditions remains to be determined. Granulocyte function should be evaluated in any infant with Sweet syndrome.     

Fatal Nodular Xaethomatosis in an Infant

We describe a unique and puzzling case of a 7-month-old baby with a non-X hypertriglyceridemic histiocytoxanthomatosis. The disease was characterized by a massive nodular eruption that was clinically, histologically, and ultrastructurally consistent with juvenile xanthogranuloma, but it had a rapid, fatal evolution.     

Refractory Pyoderma Gangrenosum in an Infant

We present a rare case of infantile pyoderma gangrenosum with an extended course and limited response to treatment. Despite extensive examination for an underlying disorder, the case remains idiopathic.     

Rituximab Induced Psoriasis in an Infant

Rituximab is a chimeric monoclonal antibody directed against the CD20 antigen present on the surface of mature B cells. It has been widely used in the treatment of many dermatologic and rheumatologic conditions. The onset of psoriasis after rituximab therapy has not been reported in children. We report the first case of psoriasis after rituximab therapy in a 16‐month‐old boy with no other risk factors for developing psoriasis.     

Giant Condyloma Acuminatum in an Infant

Abstract:   We report a 10-month-old boy who presented with a giant perianal condyloma acuminatum, and a similar lesion on the neck. These lesions were treated by surgical excision with satisfactory results. This size, extent, and early age of appearance make this case highly unusual.
