Mandibulary Eosinophilic Granuloma: Case Series
2008
Eosinophilic granuloma is a proliferation of Langerhans cells in the bones that most commonly involving the skeletal system. The disease generally affects children or young adults with predominance in males and it is characterized by a single or multiple skeletal lesions. This study describes a few cases of mandibular Eosinophilic Granuloma and the effects of surgical curettage of lesions
Sea Urchin Granuloma
2005
Sea urchin granuloma is a chronic focal response to the puncture of sea urchin spines, induced by the permanence of prickle remnants in the wound. Until recent years, it was thought to represent a foreign body reaction but, following the description, in 2001, of its several histologic forms, the spectrum of its likely pathogenetic mechanisms has widened to include the immune responses to different non-self antigens. Depending on individual reactivity, in most cases, a limited number of granulomas is observed, however numerous the punctures may be. We report a case with more than 200 lesions and a tuberculoid histologic pattern, indicative of an immune reaction.
Granulomatous mycosis fungoides, a rare subtype of cutaneous T-cell lymphoma
2015
Granulomatous mycosis fungoides (GMF) is an unusual histologic subtype of cutaneous T-cell lymphoma.1 The diagnosis of GMF is usually established after observation of a granulomatous inflammatory reaction associated with a malignant lymphoid infiltrate. Epidermotropism, a clue to diagnosis in classical mycosis fungoides (MF) may be absent in about 47% of cases of GMF.2 In some instances, the granulomatous component may be intense and obscures the lymphomatous component of the infiltrate.1 There are no distinctive clinical patterns associated with GMF.1, 3
EULAR/PRINTO/PRES criteria for Henoch-Schonlein purpura, childhood polyarteritis nodosa, childhood Wegener granulomatosis and childhood Takayasu arte…
2010
EULAR/PRINTO/PRES Objectives To validate the previously proposed classification criteria for Henoch-Schonlein purpura (HSP), childhood polyarteritis nodosa (c-PAN), c-Wegener granulomatosis (c-WG) and c-Takayasu arteritis (c-TA).Methods Step 1: retrospective/prospective webdata collection for children with HSP, c-PAN, c-WG and c-TA with age at diagnosis <= 18 years. Step 2: blinded classification by consensus panel of a representative sample of 280 cases. Step 3: statistical (sensitivity, specificity, area under the curve and.-agreement) and nominal group technique consensus evaluations.Results 827 patients with HSP, 150 with c-PAN, 60 with c-WG, 87 with c-TA and 52 with c-other were compar…
Child mandibular giant cell granuloma: Case report
2016
Giant Cell Granuloma is a rare non-odontogenic lesion. Its name derives from the presence into the tumor of giant cells, similar to osteoclasts. On the basis of the biological behaviour, there are 2 variants of this tumor differentiated between aggressive and non-aggressive lesions. Treatment options reported in the literature include marginal or segmental osteotomy. If the lesion is classified as non-aggressive the marginal osteotomy (curettage) is the adequate treatment; in contrast, in presence of aggressive lesions, segmental osteotomy (en bloc resection) appears to yield the best overall outcome. The aim of the present report was to describe a case of primary Giant Cell Granuloma of th…
Confluens-sinuum-Obstruktion durch Langerhanszell-Histiozytose
1996
Die Langerhanszell-Histiozytose, bis vor wenigen Jahren als Histiozytose X bezeichnet, umfast 3 verschiedene Syndrome, namlich das eosinophile Granulom, die Hand-Schuller-Christian-Krankheit sowie die Abt-Letterer-Siwe-Krankheit, und gehort zu den seltenen Erkrankungen des Kindesalters. Wir berichten uber einen 10 jahrigen Jungen, der mit einer Schwellung am Hinterkopf und beginnender Hirndrucksymptomatik zur stationaren Aufnahme kam. Klinik, konventionelle radiologische Diagnostik und Computertomographie liesen differentialdiagnostisch ein eosinophiles Granulom als wahrscheinlich erscheinen. MRT und MRT-Angiographie zeigten jedoch die akute Bedrohung des Patienten durch das intrakraniale W…
Úlcera eosinofílica lingual: un reto diagnóstico de patogénesis controvertida
2013
ResumenLa úlcera eosinofílica, también conocida como granuloma ulcerativo traumático con eosinofilia estromal, es una infrecuente y benigna lesión ulcerativa de la mucosa oral que presenta una evolución persistente, planteando a menudo diferentes diagnósticos clínicos diferenciales. Su diagnóstico se establece solo a partir del estudio histopatológico, si bien su morfología presenta a menudo características que pueden sugerir al patólogo la existencia de un proceso linfoproliferativo, traduciendo una patogénesis lesional controvertida todavía no bien aclarada.Comunicamos una observación clínico-patológica de úlcera eosinofílica afectando a una mujer de 76 años de edad. La lesión, de 2,5cm d…

Idiopathic facial aseptic granuloma.
2014
Summary Idiopathic facial aseptic granuloma (IFAG) is a condition that is commonly encountered in clinical practice, but is rarely reported. It appears in childhood and its pathogenesis is still unknown. It has a benign course with resolution within a few months without aggressive treatment. Microbiological tests are negative and histological findings are nonspecific. It is possible that this condition is part of the spectrum of granulomatous rosacea in childhood. We present two cases in which diagnosis of IFAG was established and resolved without sequelae following topical antibiotic treatment.
