Article Abstract
Syringocystadenoma papilliferum (SCAP), tubular apocrine adenoma (TAA), and eccrine nevus are rare benign sweat gland tumors with varied clinical presentations but generally distinctive histomorphologic profiles. TAA and SCAP have been associated with other cutaneous hamartomas, most commonly with nevus sebaceus. Additionally, TAA and SCAP have uncommonly co-occurred in the same lesion. In contrast to nevus sebaceus, eccrine nevus is considerably less common and is rarely associated with other benign adnexal lesions. Here we present an unusual case of a complex sweat gland hamartoma containing features of syringocystadenoma papilliferum, tubular apocrine adenoma, and eccrine nevus in a 7-year-old female.

The assessment of adrenergic modulation of sweating as assessed via pharmacologic administration of α- and β-adrenergic receptor blockers during exercise has yielded mixed findings. However, the underlying mechanisms for this disparity remains unresolved. We investigated the effects of separate and combined blockade of α- and β-adrenergic receptors on forearm sweating induced by a 30-min moderate-intensity exercise bout (n=17, protocol 1) and the administration of adrenergic agonists epinephrine and norepinephrine (n=16, protocol 2) in the heat.

Hamartoma is characterized by the abnormal proliferation of cells and tissues within the originating organ. Apocrine hamartoma (AH) affecting the skin, especially in the perianal area, has not yet been reported in dogs. A 7-year-old neutered male Poodle presented with multiple perianal papules and pruritus.

Eruptive syringoma, a rare subtype of syringoma, is a benign adnexal tumor arising from the eccrine sweat glands. It is characterized by multiple asymptomatic, flat-topped, brown-pigmented papules. The disease typically occurs during adolescence and young adulthood.

Background/objectives: Hidrocystomas, eccrine and apocrine, are rare cystic lesions that form benign tumors of the sweat glands. This study aimed to describe the clinical features of hidrocystomas and evaluate the role of non-invasive imaging techniques, including dermoscopy, Line-field Confocal Optical Coherence Tomography (LC-OCT), Reflectance Confocal Microscopy (RCM), and Ultra-High-Frequency Ultrasound (UHFUS), in their diagnosis.
Methods: In total, seven cases of hidrocystomas were collected from the Dermatologic Clinic of the University of Siena, Italy.

Mammalian skin appendages, such as hair follicles and sweat glands, are essential for both esthetic and functional purposes. Conditions such as burns and ulcers can lead to dysfunction or loss of skin appendages and result in hair loss and dry skin, posing challenges in their regeneration. Existing animal models are insufficient for studying acquired dysfunction of skin appendages without underlying genetic causes.
