Cutis marmorata telangiectatica congenita is an uncommon congenital vascular anomaly that is characterized by persistent, reticulated, violaceous pigmentation. We describe a female infant with vascular lesions consistent with this entity who was born to a mother with previously diagnosed systemic lupus erythematosus. Antinuclear antibodies and anti-Ro/SSA antibodies were detected in both mother and infant, supporting a diagnosis of neonatal lupus. This presentation is consistent with the rarely reported association between neonatal lupus and cutis marmorata telangiectatica congenita that suggests the latter is part of the cutaneous spectrum of the former. A thorough maternal history and laboratory investigations should be considered for infants with cutis marmorata telangiectatica congenita and their mothers in order to rule out the presence of an underlying autoimmune disease.

Comprehensive insights of Sneddon syndrome: A clinical perspective.
J Cent Nerv Syst Dis
December 2024
Faculty of Medicine, The Hashemite University, Zarqa, Jordan.
Background: Sneddon's syndrome is a rare thrombotic vasculopathy characterized by the coexistence of both cerebrovascular events and livedo reticularis.
Objective: This review aims to raise awareness among physicians by discussing the whole clinical spectrum of the disease. Typically, Sneddon syndrome presents in middle-aged women with a cerebrovascular accident and a preexisting skin rash, which is livedo reticularis.
Vascular Disturbances of the Skin in Critically Ill Patients: Lines, Dots, Patches.

When an understanding of pathogenesis exists, skin lesions that have the appearance of blood in the skin can provide insight into the mechanisms leading to a systemic process that results in cutaneous manifestations. Of the vascular disturbances of the skin that occur in critically ill patients, some result from a non-hemorrhagic process while occurs represent bleeding into the skin. The lesions of livedo, petechiae, purpura, and ecchymoses can be approached from such a perspective.

Chronic leg ulceration is a debilitating manifestation of hemoglobinopathies, and best management is uncertain. Livedoid vasculopathy (LV) is a cutaneous non-inflammatory thrombotic vasculopathy treated with anticoagulation that has been identified in hemoglobinopathy-associated chronic leg ulceration. However, most patients with hemoglobinopathy-associated ulcers do not undergo workup for secondary causes, and the prevalence and relevance of LV is unclear.

Department of Dermatology, Fukushima Medical University, Fukushima.
While the skin is a common target organ for sarcoidosis, cutaneous granulomatous vasculitis is rare among patients with sarcoidosis. Due to the lack of detailed studies on cutaneous sarcoid vasculitis, both dermatologists and pathologists remain unfamiliar with this rare but important vasculitic disorder. We clinicopathologically evaluated eight cases with biopsy-proven cutaneous vasculitis and cutaneous sarcoidosis and analyzed morphologic changes in the process of vasculitis for both small vessels and muscular vessels in detail.
