Pubertal retroareolar cysts presenting as bluish lumps: New cases and literature review.

Retroareolar cysts (RCs) are a benign self-resolving condition primarily affecting pubertal individuals. However, their presentation as asymptomatic bluish areolar lumps remains underreported in the literature, with only six cases previously documented. This lack of awareness may lead to the oversight of RCs during diagnosis.

Relapsing subcutaneous nodules of the penis in a pediatric patient.

A 14-year-old boy presented with a history of non-tender, subcutaneous coalescing nodules located on the ventral-lateral aspects of the penis shaft for one year. Laboratory investigations for blood count and autoimmunity were within normal limits. Complete excision was performed, and on histology, the dermis showed necrobiotic material composed of altered collagen bundles, surrounded by a palisade of histiocytes and scattered lymphocytes, thus allowing a diagnosis of subcutaneous granuloma annulare.

Transient abdominal telangiectasia of the newborn: Four new cases with abdominal distension.

Transient abdominal telangiectasia of the newborn (TATN) is a recently described entity. The majority of cases had no specific clinical context or trigger identified, but a minority occurred in the clinical context of transient increased intraabdominal pressure. We report four additional cases of TATN, all in the presence of transient abdominal distension, further supporting the causative relationship of abdominal distension to TATN.

Surgical management of large scalp infantile hemangioma in 30-month-old infant.

Infantile Hemangiomas (IH) are the most common benign tumor of infancy, occurring in over 10% of newborns. The head and neck is the most frequently affected area (60%), and the scalp is a typical site for such large lesions. Scalp-IHs are usually focal lesions that can be both disfiguring and may lead to complications such as ulceration and bleeding.

Papulo-purpuric dermatitis of childhood: a distinct PLEVA-like eruption associated to SARS-CoV-2 infection. Clinical, histopathological and immunohistochemical study of 10 cases.

We observed ten children with a papular eruption with purpuric features during the SARS-CoV-2 pandemic in Northern Italy (May-December 2020). Histological examination showed signs of SARS-CoV-2-related dermatosis. Evidence of nucleocapsid viral proteins using SARS-CoV-2 (2019-nCoV) nucleocapsid antibody revealed cuticular staining of the deep portion of the eccrine glands in all cases.

The Trichoscopic "Golf Club Set" Sign for Bullous Aplasia Cutis Congenita.

Bullous aplasia cutis congenita (BACC) is a rather uncommon entity. The diagnosis can be quite tricky as the entity is not very frequent. Trichoscopy might in these cases be helpful to achieve the correct diagnosis.

The Dermoscopic "Pluck Out Sign" for Beard Trichotillomania.

Beard trichotillomania (TTM) is a rather uncommon entity. Hair is not easily plucked from the beard area, as patients need forceps or tweezers to perform their task. The diagnosis of beard TTM can be quite tricky as the location is not the most frequent one.

Cardiac arrest in a toddler treated with propranolol for infantile Hemangioma: a case report.

Background: Propranolol has become the first-line treatment for complicated Infantile Hemangioma (IH), showing so far a good risk-benefit profile.

Case Presentation: We report the case of a toddler, on propranolol, who suffered cardiac arrest during an acute viral infection. She had a neurally-mediated syncope that progressed to asystole, probably because of concurrent factors as dehydration, beta-blocking and probably individual susceptibility to vaso-vagal phenomena.

Safety and effectiveness of oral propranolol for infantile hemangiomas started before 5 weeks and after 5 months of age: an Italian multicenter experience.

Background: Despite not being licensed for the treatment of infantile hemangiomas (IH) in infants younger than 5 weeks or older than 5 months, propranolol is often used in these age groups to prevent or to treat potentially severe complications. The objective of the present study was to review the experience of 8 Italian pediatric and dermatologic centers regarding propranolol treatment for IH started before 5 weeks or after 5 months of age.

Methods: We retrospectively reviewed the records of patients followed up for IH, on propranolol treatment started before 5 weeks or after 5 months of age, and collected information on sociodemographic data, treatment indications, IH involution, IH relapse, and treatment side effects.

Rapid containment of nosocomial transmission of a rare community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) clone, responsible for the Staphylococcal Scalded Skin Syndrome (SSSS).

Background: The aims of this study were to identify the source and the transmission pathway for a Staphylococcal Scalded Skin Syndrome (SSSS) outbreak in a maternity setting in Italy over 2 months, during 2014; to implement appropriate control measures in order to prevent the epidemic spread within the maternity ward; and to identify the Methicillin-Resistant Staphylococcus aureus (MRSA) epidemic clone.

Methods: Epidemiological and microbiological investigations, based on phenotyping and genotyping methods, were performed. All neonates involved in the outbreak underwent clinical and microbiological investigations to detect the cause of illness.
