Sebaceous Hyperplasia (sebaceous + hyperplasia)
Selected AbstractsMelanocytic nevi are associated with neurofibromas in neurofibromatosis, type I, but not sporadic neurofibromas.JOURNAL OF CUTANEOUS PATHOLOGY, Issue 8 2005A study of 226 cases Background:, Neurofibromatosis, type 1, is associated with cutaneous melanin pigmentation, but an association with ordinary melanocytic nevi has not been described. Methods:, This retrospective case-control study was designed to see if neurofibromas in patients with neurofibromatosis, type 1 (NF-1) differ from sporadic neurofibromas (SN) in their incidence of associated melanocytic nevi and other histologic features. Slides from 114 NF-1 were compared with 112 SN and 300 intradermal melanocytic nevi (IDN). Results:, Small lentiginous melanocytic nevi were identified over 13 NF-1 (11%) but no SN (P = 0.0002). Compared with other NF-1, NF-1 with nevi were more frequently associated with melanocytic hyperplasia, giant melanosomes and diffuse neurofibroma (P < 0.03). Compared with SN, NF-1 were also more frequently associated with melanocytic hyperplasia, lentigo simplex-like changes, diffuse neurofibroma and plexiform neurofibroma (P < 0.001). Sebaceous hyperplasia (14%), dermal elastosis (9%), lipomatous change (8%), epithelial cysts (4%) and keratin granulomas or folliculitis (3%) were not significantly different in prevalence between NF-1, SN and the control group of IDN. Conclusions:, This study suggests that there is a difference in the potential for melanocytic proliferation in NF-1 compared with SN. NF-1, SN and IDN are associated with a similar range of incidental histologic changes.

This is also the first reported case of unilateral sebaceous hyperplasia occurring in a male, as plaque morphology. [source] Prevalence of Cutaneous Findings in Hospitalized Neonates: A Prospective Observational StudyPEDIATRIC DERMATOLOGY, Issue 2 2009Ayten Ferahbas M.D. Methods:, All of newborn infants hospitalized in the Newborn Unit of Erciyes University Medical School Hospital in Central Anatolia, Turkey from February 1 to November 30, 2003, were included prospectively in the study. A questionnaire regarding maternal gestational history, maternal and family history was administered to the parents of each child. All skin lesions were recorded and mapped on a body chart. Results:, Of the 816 newborns, parents of 650 gave informed consent. Only 28 (4.3%) of the infants had no dermatologic examination findings. The most common 10 diagnoses were: xerosis/desquamation 257 (39.5%), sebaceous hyperplasia 207 (31.8%), transient toxic erythema 201 (30.9%), salmon patch 125 (19.2%), Mongolian spot 86 (13.2%), cutis marmorata 69 (10.6%), suction bulla 67 (10.3%), miliaria 55 (8.5%), hypertrichosis 51 (7.8%), and dermatitis (irritant, seborrheic, or diaper) 14 (2.1%). Conclusions:, This study confirms that skin changes in the newborn are common, particularly desquamation, sebaceous hyperplasia, and transient toxic erythema. [source] | ||||||||||
