RESUMEN
Ointment pseudo-cheilitis is a recently recognized distinctive type of self-induced cheilitis. Lesions consist of a variable amount of crusts adhered to the vermilion. These crusts consist of dried saliva and dead cells mixed with applied medications attached to the lip surface. Patients are typically severely anxious or depressed; the condition impacts quality of life. Ointment pseudo-cheilitis is frequently misdiagnosed as exfoliative cheilitis or cheilitis glandularis. Biopsy reports are often non-revealing because there are no established histopathological criteria for this disease, and clinicians usually do not formulate the correct diagnostic hypothesis. Here, we present the histopathological findings of four cases of ointment pseudo-cheilitis. The most consistent finding was the presence of laminated parakeratotic material detached from the epithelium in biopsies that are devoid of other significant diagnostic changes. This material at the lip surface possibly represents physiologic labial desquamation mixed with dried saliva and applied medication. With this report, we intend to alert dermatopathologists to the diagnosis of ointment pseudo-cheilitis if they receive biopsies from patients who present clinically exuberant labial lesions that show only minimal histopathological changes.

Disseminated cryptococcosis, commonly linked to immunocompromised conditions like HIV infection, is exceedingly rare in immunocompetent individuals. This case report presents a rare case of disseminated cryptococcosis in an immunocompetent patient, who manifested with fever, weight loss, neurological manifestations, and distinct verrucous skin lesions. Mycological cultures and histopathological assessments were conducted, leading to the identification of Cryptococcus neoformans var. gattii within both lung and skin biopsies. This case highlights the significance of considering this yeast infection within immunocompetent individuals and the necessity for promptly initiating appropriate antifungal therapy to enhance patient outcomes.
RESUMEN
A 43-year-old female with advanced HIV infection presented with two chronic skin lesions. Cutaneous cryptococcosis was confirmed and pulmonary cryptococcosis was suspected. The patient was neurologically asymptomatic and the cerebrospinal fluid cryptococcal antigen lateral flow assay was negative. She received oral fluconazole and had resolution of the skin lesions and significant improvement of the lung lesions. We report a person with AIDS with chronic disseminated cryptococcosis without meningeal involvement successfully treated with oral fluconazole.
RESUMEN
Currently, pagetoid dyskeratosis is believed to involve an accelerated keratinization process, possibly induced by mechanical trauma. It represents, in almost its totality, incidental histological findings of specific cells, except when it occurs in the hands, where it usually occurs simultaneously with skin lesions and local dyschromia. These are large, rounded keratinocytes, with pale cytoplasm and a pyknotic nucleus surrounded by a clear halo, which can be easily mistaken by other skin diseases. Its etiology is not completely elucidated, and the correct identification of this entity can be of great importance in the differential diagnosis of skin disorders and the understanding of the keratinization process of the epidermis.
