[Dermatotoxicity caused by Chrysaora hysoscella. Presentation of a case]
Summary
Chrysaora hysoscella, a rarely seen Adriatic jellyfish, can cause skin reactions. Documented cases show this jellyfish exhibits dermotoxic effects, causing itching and lesions upon contact.
Area of Science:
- Marine Biology
- Toxicology
- Dermatology
Background:
- Chrysaora hysoscella is infrequently found in the Adriatic Sea and generally considered harmless.
- Previous reports on its effects are scarce, potentially due to its rarity and misidentification with other jellyfish species.
Observation:
- A marine biologist experienced itching and erythema on her hands after handling Chrysaora hysoscella tentacles and oral arms.
- Experimental application of a Chrysaora hysoscella tentacle to volunteer skin induced itching, burning, and erythematous vesicular lesions.
Findings:
- The study provides documented evidence of the dermotoxic potential of Chrysaora hysoscella.
- Contact with Chrysaora hysoscella can lead to localized skin reactions, including itching, burning, and visible lesions.
Implications:
- This research highlights the need for caution when encountering Chrysaora hysoscella, even if considered innocuous.
- Accurate identification of jellyfish species is crucial for understanding and managing potential envenomations.

Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
