Rhabdomyomatous Mesenchymal Hamartoma: A Deep Subcutaneous Lesion in the Sternoclavicular Area.

Cutaneous rhabdomyomatous mesenchymal hamartoma (RMH) is a rare benign tumor composed of two or more types of mesenchymal-derived cells. RMHs are generally sporadic and independent, but they can be associated with congenital abnormalities. We report a subcutaneous case of RMH in the sternoclavicular area with two recurrences after complete surgical excision.

Analysis of POU5F1, c-Kit, PLAP, AP2γ and SALL4 in gonocytes of patients with cryptorchidism.

Cryptorchidism is a risk factor for the development of testicular germ cell tumors (TGCTs). The most common type of TGCT in cryptorchidism is seminoma. The intratubular germ cell neoplasia unclassified (ITGCNU) is a histological pattern preceding the development of seminomas and non-seminomas.

Neonatal vesiculopustular eruption associated with transient myeloproliferative disorder: report of four cases.

Background: Transient myeloproliferative disorder (TMD) affects up to 10% of patients with Down syndrome (DS). A small proportion of newborns are asymptomatic and only manifest circulating blast cells, with or without leukocytosis, while others present with hepatomegaly, splenomegaly, serous effusions, and liver fibrosis. Few cases in the literature also have skin manifestations, described as crusted, erythematous, vesiculopustular eruptions occurring mainly on the face, with spreading to the trunk and extremities.

Treatment of Kimura disease with intravenous immunoglobulin.

Kimura disease is an uncommon chronic inflammatory condition of unknown etiology and is characterized by painless subcutaneous nodules, usually affecting the head and neck, eosinophilia, and markedly elevated immunoglobulin E levels. Several reports have described the main modalities of treatment; both corticosteroids and surgery have provided good results, but occasionally corticosteroids cannot be tapered as the disease flares up. We report here the case of an 8-year-old boy diagnosed with Kimura disease who was successfully treated with 1 dose of intravenous immunoglobulin as a steroid-sparing agent.
