Newborn skin nodules are usually benign and self-resolving skin condition. Differential diagnosis of such lesions include cysts, hemangioma, abscess, cellulitis, sclerema neonatorum, subcutaneous fat necrosis, neurofibromatosis, benign tumors, or malignant tumors such as rhabdomyosarcoma, infantile fibrosarcoma, or neuroblastoma. We report a case of congenital subcutaneous fat necrosis in a 7-day-old baby presenting with multiple erythematous mass on back. Read More

Subcutaneous fat necrosis of the newborn is an uncommon disorder, and although usually benign, associated hypercalcemia can lead to complications such as failure to thrive and renal failure. Many sources suggest screening for hypercalcemia for 6 months following resolution of skin lesions, but little data are available to support this recommendation. This study examines existing published literature to better guide practitioners regarding screening evaluations of asymptomatic patients with subcutaneous fat necrosis. Read More

Subcutaneous fat necrosis of the newborn is a rare benign panniculitis found in term and post-term neonates. Diagnosis is based on clinical characteristics and specific alterations in the adipocytes, detected by anatomical pathology. Subcutaneous fat necrosis of the newborn can occur in uncomplicated pregnancy and childbirth. Read More

Subcutaneous fat necrosis of newborn is a form of noninfectious panniculitis. It is an uncommon condition and mostly occurs in full-term infants within first weeks of life that have had a significant condition such as hypoxic-ischemic encephalopathy at the time of birth. Subcutaneous fat necrosis of newborn is usually a self-limiting condition but may be associated with hypercalcemia, which may lead to life threatening levels. Read More

Subcutaneous fat necrosis of the newborn is an uncommon, transient, and self-healing panniculitis, mostly affecting term newborns with perinatal complications. The authors present a case of a female full-term neonate, born from an uncomplicated pregnancy, admitted into the neonatology unit 5 hours after delivery because of refractory multifocal seizures in the context of hypoxic-ischemic encephalopathy. Nine days after birth, indurated and erythematous nodules and plaques were noted on the left arm and back. Read More

Subcutaneous fat necrosis of the newborn (SCFNN) is a rare benign inflammatory disorder of the adipose tissue but may be complicated by hypercalcemia or less frequently, hypocalcemia, resulting in morbidity and mortality. Here we report the case of a neonate with subcutaneous fat necrosis who surprisingly developed hypocalcemia instead of hypercalcemia. A full-term female neonate was delivered by emergency cesarean section for fetal distress and was subsequently admitted to the Special Care Baby Unit. Read More

Subcutaneous fat necrosis of the newborn (SFNN) is a rare disorder characterised by indurated plaques or nodules with or without erythema, typically distributed over the cheeks, extremities, posterior trunk, buttocks, and thighs, and appears during the first 2 weeks of life. It is commonly associated with perinatal asphyxia and, while usually self-limited, can lead to severe hypercalcemia. There is no known familial association. Read More

Subcutaneous fat necrosis of the newborn (SCFN) is a rare, self-limited disorder of the panniculus which appears in the first few weeks of life. SCFN generally follows an uncomplicated course. However, there are important complications for which the patient must be regularly monitored, including thrombocytopenia, hypoglycemia, hypertriglyceridemia, and most importantly, hypercalcemia.

The diagnosis of panniculitis is felt to be a confusing topic by some pathologists. This summarical article presents inflammatory diseases of the subcutis in a systematic fashion, based on whether they are centered on fibrovascular septa or the adipose lobules, and whether morphologic vasculitis is present or not. Septocentric, non-vasculitis disorders include erythema nodosum, panniculitis that follows the use of "biological" therapeutic agents, lipodermatosclerosis, post-irradiation panniculitis, morphea profunda, and necrobiosis lipodica profunda.

Subcutaneous fat necrosis of the newborn (SFN) is a rare form of panniculitis that can be complicated by hypercalcemia and nephrocalcinosis. We conducted a 20-year retrospective cohort study of 30 patients to describe the clinical characteristics of SFN and the prevalence of hypercalcemia and other complications. Hypoxia and therapeutic hypothermia (TH) seem to play an important role in the development of SFN. Read More

Panniculitis is an inflammation of the subcutaneous fat. Skin biopsy plays a critical role in the differential diagnosis of panniculitis. The most common approach to diagnosis relies on the differentiation between predominantly septal or lobular panniculitis, followed by the distinction between lesions with and without vasculitis.

Background: The inflammatory infiltrate seen in biopsy specimens obtained from patients with subcutaneous fat necrosis of the newborn (SCFN) has classically been described as consisting mostly of histiocytes. However, we encountered patients with SCFN whose biopsy specimens revealed mostly neutrophils, prompting infection to be an initial consideration.

Objectives: We sought to describe cases of SCFN in which neutrophils formed the majority of the infiltrate at our institution and in the literature. Read More

Therapeutic hypothermia is the current standard treatment in newborns with moderate to severe hypoxic-ischemic encephalopathy, changing the outcome of these children. It is considered a safe technique with almost no side effects. A possible adverse side event is subcutaneous fat necrosis, which is an acute self-limiting panniculitis that develops during the first weeks of life. Read More

Subcutaneous fat necrosis (SCFN) of the neonate is a rare panniculitis of early life that occurs in association with gestational diabetes and preeclampsia, as well as perinatal asphyxia, hypothermia, and trauma. A characteristic feature of this condition is its self-limiting and monophasic nature. We report a highly unusual case of delayed SCFN in a male neonate involving an anatomically discrete eruption, reminiscent of erythema nodosum, occurring many weeks after his original eruption had resolved.

Background: Moderate cooling after birth asphyxia is associated with substantial reductions in death and disability, but additional therapies might provide further benefit. We assessed whether the addition of xenon gas, a promising novel therapy, after the initiation of hypothermia for birth asphyxia would result in further improvement.

Methods: Total Body hypothermia plus Xenon (TOBY-Xe) was a proof-of-concept, randomised, open-label, parallel-group trial done at four intensive-care neonatal units in the UK. Read More

Panniculitis with lipid crystallization within adipocytes may be seen in several disorders, including crystal-storing histiocytosis, gouty panniculitis, subcutaneous fat necrosis of the newborn, post-steroid panniculitis, sclerema neonatorum, oxalosis and subcutaneous fungal infections by mucormycosis, zygomycosis or aspergillosis. Panniculitis at the sites of subcutaneous injection of drugs are frequent, but to our knowledge no crystals have been described in the drug-induced panniculitis at the sites of subcutaneous injections. We report on a patient who developed a panniculitis with lipid crystallization at the site of etanercept injection. Read More

Since the introduction of therapeutic hypothermia for HIE, there have been a few published case reports of SCFN, following this modality of treatment. Although, most cases of SCFN resolve spontaneously, SCFN may be associated with hypercalcemia, which may sometimes reach dangerous levels. Read More
