Dowling lattices and their generalizations introduced by Hanlon are interpreted as lattices of congruences associated to certain quasi-varieties of sets with group actions. This interpretation leads, by a simple application of Mobius inversion, to polynomial identities which specialize to Hanlon's evaluation of the characteristic polynomials of generalized Dowling lattices. Analogous results ar...
Clear cell acanthoma or Degos' acanthoma is a distinct disease concerning its clinical, histopathological, and immunohistochemical features. Its pathologic nature - whether neoplastic or reactive - is still under dispute among researchers. The disease shows a chronic course and often presents with a single papulonodular lesion on the lower limbs of adults. However, cases with multiple lesions, ...
Abstract Background Degos disease is a rare vascular disorder with cutaneous-limited form, benign atrophic papulosis (BAP), and systemic variant, malignant (MAP). Despite the poor prognosis of MAP, no study has established features associated disease. Objectives The aims this systematic review were to: (1) summarize clinical treatments implemented for patients MAP BAP (2) identify laboratory fa...
Degos disease is an extremely rare disease, manifesting in the skin as necrotic papules. It may be skin-limited but prognosis poor for systemic involvement. primarily considered a microthrombopathy, pathophysiology remains elusive and lacks effective treatments. We found prominent lymphocytic infiltration targeting epidermis vasculature lesional of patients, suggesting immune-mediated pathophys...
A finite subgeometry of a Dowling geometry for an infinite group is exhibited, which cannot be embedded in a Dowling geometry for any finite group; this provides a negative answer to a question of Bonin. The question addressed herein is motivated by the following fundamental result of Rado, concerning the embeddability of finite geometries in projective geometries [Ra, Theorem 4]: Theorem. Ever...
A 4-year-old boy developed a headache. Initial evaluation revealed a normal neurologic examination and a right subdural hygroma on CT. Worsening headaches led to hospitalization at an outside institution. MRI showed leptomeningeal enhancement; magnetic resonance angiography (MRA) was normal. Infectious, rheumatologic, hematologic, and CSF studies were unrevealing. He then developed a left-sided...
