BACKGROUND: Ichthyosis uteri is a rare pathological condition characterized by the replacement of the endometrial lining by stratified squamous epithelium. Yet its occurrence with endometrial adenocarcinoma is very rare.
METHODS: A 68-year-old woman has been experiencing sporadic, minor vaginal hemorrhages for a few months. The gynecological evaluation revealed a uterine enlargement and imaging demonstrated an irregular mass within the uterus.
METHODS: Endometrial adenocarcinoma with transitional cell differentiation; ichthyosis uteri with dysplasia.
METHODS: Radical hysterectomy with pelvic lymphadenectomy was performed followed by postoperative radiotherapy.
RESULTS: Postoperative follow-up at 8 months showed a favorable outcome without signs of recurrence and metastasis.
CONCLUSIONS: Adequate pathological sampling is crucial to identifying the accompanying lesions of ichthyosis uteri. Finding molecular alterations in various pathological morphologies is important to understand the evolution of disease.

Dermatophyte infections frequently pose diagnostic challenges, especially when occurring alongside ichthyosis, a genetic skin disorder characterized by dry, thickened, scaly skin. This case series outlines three cases where dermatophyte infections overlapped with ichthyosis, emphasizing the complexities in clinical identification and differential diagnosis. Atypical clinical presentations in these cases led to initial misdiagnoses. Ichthyosis, a genetic skin disorder characterized by thickened and scaly skin, creates an environment conducive to dermatophyte settlement, complicating the diagnostic process. The cases highlight the importance of considering fungal infections, even when clinical features deviate from the expected course. A vigilant diagnostic approach, including mycological examinations, is crucial for accurate identification and timely management.

HELIX syndrome (Hypohidrosis-Electrolyte disturbances-hypoLacrimia-Ichthyosis-Xerostomia) (MIM#617671) (ORPHA:528105), described in 2017, is due to an abnormal claudin 10 b protein, secondary to pathogenic CLDN10 variants. So far, only ten families have been described. We aim to describe the phenotype in the first Spanish family identified, highlight the skin anomalies as an important clue, and expand the genotypic spectrum. Two adult brothers from consanguineous parents with suspected ectodermal dysplasia (ED) since early childhood were re-evaluated. A comprehensive phenotypic exam and an aCGH + SNP4 × 180 K microarray followed by Sanger sequencing of the CLDN10 gene were performed. They presented hypohidrosis, xerosis, mild ichthyosis, plantar keratosis, palm hyperlinearity, alacrima, and xerostomia. In adulthood, they also developed a salt-losing nephropathy with hypokalemia and hypermagnesemia. The molecular study in both patients revealed a novel pathogenic homozygous deletion of 8 nucleotides in exon 2 of the CLDN10 gene [CLDN10 (NM_0006984.4): c.322_329delGGCTCCGA, p.Gly108fs*] leading to a premature truncation of the protein. Both parents were heterozygous carriers. Hypohidrosis, ichthyosis, and plantar keratosis associated with alacrima and xerostomia should raise suspicion for HELIX syndrome, which also includes nephropathy and electrolyte disturbances in adults. Given the potential for ED misdiagnosis in infancy, it is important to include the CLDN10 gene in a specific genodermatosis next-generation sequencing (NGS) panel to provide early diagnosis, accurate management, and genetic counseling.

Epidermal nevi are common benign cutaneous hamartomas that may rarely demonstrate histopathologic evidence of epidermolytic hyperkeratosis (EHK), representing cutaneous mosaicism for pathogenic keratin variants. Rarely, individuals with linear epidermal nevi transmit to their children the inherited form of EHK, also known as epidermolytic ichthyosis, characterized by generalized erythema, blistering, and scaling at birth evolving to widespread hyperkeratosis. We present an updated review of reported cases of linear epidermal nevi with EHK exhibiting transmission of epidermolytic ichthyosis to guide important considerations in the care of individuals with epidermal nevi. Clinical characteristics of linear epidermal nevi do not reliably predict the presence of EHK. All reported cases of transmission to offspring have occurred in individuals with linear epidermal nevi involving more than one anatomic area suggesting increased reproductive risk with involvement of two or more anatomic sites. Therefore, genetics consultation is recommended for these individuals with biopsy-confirmed EHK. For individuals with smaller areas of epidermal nevus involvement, the implications are less well known, though genetics consultation may still be considered for those interested in further discussion of general reproductive risk.

Chanarin-Dorfman syndrome (CDS) is a multisystem autosomal recessive disorder due to variants of the ABHD5 gene, characterized by lipid vacuoles in the liver and leukocytes, and possible involvement of eyes, ears, skeletal muscle, and central nervous system. CDS may present with skin changes, most commonly congenital non- bullous ichthyosiform erythroderma, however erythrokeratoderma-like findings have been rarely reported in CDS patients. Herein, we report clinical, histopathological and genetic findings of four patients with CDS presenting with different clinical forms of erythrokeratoderma (three with progressive symmetric erythrokeratoderma-like features and one with erythrokeratoderma variabilis (EKV)-like features), including one patient with a novel mutation in ABHD5. Although the typical skin finding of CDS syndrome is reported as non-bullous congenital ichthyosiform erythroderma, CDS should also be in the differential diagnosis in patients with EKV-like lesions.

BACKGROUND: Kava, a substance derived from the Piper methysticum plant, is enjoying a surge in popularity in the United States due to its purported anxiolytic and analgesic effects. Though ichthyosiform dermopathy is a known adverse effect associated with chronic kava exposure in adults, dermopathy in a newborn due to maternal kava use has not yet been described.
METHODS: This is a case of a 41-year-old woman who was taking a combination kava/kratom product throughout her pregnancy. She developed an ichthyosiform dermopathy that resolved after she stopped using the product postpartum. Her male infant had a neonatal course complicated by both neonatal opioid withdrawal syndrome, attributed to maternal kratom and buprenorphine use, as well as a diffuse ichthyosiform rash similar to descriptions of kava ichthyosiform dermopathy in adults. His neonatal course was complicated by Group B streptococcus and Serratia marscecens bacteremia (treated with antibiotics) and seizures (treated with lorazepam and phenobarbital). His rash resolved completely by day of life 22. At 9-month outpatient follow-up, he had no dermatologic abnormalities or rash recurrence.
CONCLUSIONS: Maternal kava use during pregnancy may cause fetal dermopathy presenting as an acquired ichthyosis. More public education is needed about the potential consequences of kava use, particularly during pregnancy.
