Drug rash, eosinophilia, and systemic symptoms (DRESS) syndrome is a severe systemic hypersensitivity reaction that usually occurs within 6 weeks of exposure to the offending drug. Diagnosis is usually straightforward in patients with pyrexia, skin rash, hepatitis, and eosinophilia with a preceding history of exposure to agents often associated with DRESS syndrome, such as aromatic anticonvulsants and sulfa drugs, but diagnosis of DRESS may still be a challenge. We report a 4-year-old child with probable DRESS syndrome complicated by multiple hematologic complications that developed 1 month after exposure to fluoxetine, a drug not known to be associated with such severe reactions.

Carcinoma of the penis has a well documented metastatic pattern, regional lymph nodes being the predominant site of involvement. Distant metastasis is extremely rare, with a reported incidence of 1-10%. Osseous metastasis is even rarer and no case of metastasis to the spine has been reported previously. We present a case of carcinoma of the penis metastasizing to the spine.

This study determined the prevalence of autism spectrum disorders in 201 siblings of children with autism spectrum disorders. Siblings were screened using Modified Checklist for Autism in Toddlers and Social Responsiveness Scale, parent version. Screen-positive siblings were assessed using Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) criteria. The risk of autism spectrum disorder in siblings was correlated with various familial and disease characteristics of the index case. Prevalence of autism spectrum disorder in siblings was 4.97%. There was a significant effect of the presence of aggressive behavior, externalizing problems and total problems in the proband, assessed using Childhood Behavior Checklist, and the young age of the father at conception on sibling risk of autism spectrum disorder. Results of our study are in line with previous studies reporting similar prevalence but have also brought up the association with behavioral problems as a possible risk factor. Siblings of children with autism spectrum disorder should be routinely screened, and genetic counseling for this increased risk should be explained to the family.

Ewing sarcoma (ES) is a malignant round cell tumour (MRCT) that usually involves bone and soft tissue of young and paediatric populations. ES of the head and neck region is uncommon. Adamantinoma-like Ewing sarcoma (ALES) is a rare variant of ES that shows complex epithelial differentiation on histopathology and immunohistochemistry (IHC). It demonstrates a t(11;22) translocation and EWSR1-FLI1 fusion. Most documented cases of ALES of the head and neck region were initially misdiagnosed as epithelial tumours. We present a rare case of ALES of the nasal cavity in a young female. The patient subsequently underwent chemotherapy and showed an excellent response. Awareness of this entity is important for pathologists and oncologists due to its distinct therapeutic and prognostic implications. We propose performing upfront NKX2.2 and CD99 IHC studies, as well as other lineage specific IHC markers, in any poorly differentiated MRCT of head and neck region.
