Toxic epidermal necrolysis (TEN) is a rare, life-threatening dermatological emergency characterized by extensive epidermal necrosis and detachment, along with significant mucous membrane erosions and systemic symptoms. While conventional medications such as sulfonamides and anticonvulsants are known triggers, recent reports suggest that herbal medications can also induce TEN. This case report highlights the development of TEN in a patient with invasive cervical cancer following the use of an herbal supplement.

A 48-year-old Filipino woman with newly diagnosed invasive cervical cancer developed TEN after taking an herbal supplement containing 23 botanical extracts. Despite discontinuing the supplement, her condition rapidly worsened, with vesicles and bullae progressing to epidermal detachment over 90% of her body surface area. A histopathological examination confirmed the diagnosis of TEN. The patient was treated with systemic corticosteroids and supportive care, achieving full recovery within 14 days.

This case underscores the potential risks associated with herbal medications, particularly in vulnerable patients such as those with cancer. Although conventional pharmaceuticals are the primary culprits for TEN, this report highlights the need for greater awareness of herbal medicine-induced adverse drug reactions. Underreporting of such events, due to lack of awareness among patients and healthcare providers, further complicates the issue. This case emphasizes the need for strengthened regulatory policies and enhanced education to safeguard public health amidst the increasing use of herbal remedies worldwide.

A total of 336 patients suspected of having allergic contact dermatitis underwent patch testing at our institution from August 2000 to February 2005 using the European Standard Series by Chemotechnique Diagnostics composed of 25 allergens. The cutaneous lesions were located on the hands (46.2 percent), feet (29.1 percent), arms (25.5 percent), legs (21.0 percent) and trunk (15.9 percent). Patch test results showed that 303 (90 percent) had one or more positive patch test reaction. The most frequent positive reactions were to nickel sulfate (42 percent), potassium dichromate (30.7 percent), cobalt chloride (25.5 percent), parabens (22.5 percent) and fragrance mix (18.65 percent) while the least frequent were Tixocortil-21-pivalate (33 percent), Quarternium -15 1.0 percent pet (3 percent), Budesonide (2.7 percent) and Quinolone mix 6.0 percent pet (2.7 percent). In this study the most frequent relevant sources for nickel sulfate were keys/keychains, costume jewelry, coins and watches. For potassium dichromate the top sources were adhesives, detergents and leather. The most common sources for cobalt chloride were zippers/buttons and jewelry. For parabens the relevant sources were food products and cosmetics while for fragrance mix these were cosmetics and fragrances.

Lamellar Ichthyosis (LI) is a rare autosomal recessive disorder caused by mutations in genes, primarily TGM1, that affect skin barrier formation. It results in large, hyperpigmented, plate-like scales covering the entire body and persists throughout life. This case illustrates the chronic and debilitating nature of LI, highlights therapeutic approaches that improve quality of life, and emphasizes the importance of genetic testing in managing the condition.

Patient A, a 25-year-old female, and Patient B, a 22-year-old male, are Filipino siblings from non-consanguineous parents with no notable family history. Both were born encased in a collodion membrane that later revealed generalized erythema with large scales and deep fissures. As they aged, symptoms worsened, including reduced sweating, heat intolerance, ectropion, eclabium, cicatricial alopecia, palmoplantar hyperkeratosis, limited finger movement, and blurred vision from corneal scarring. Whole exome sequencing identified a homozygous pathogenic variant in the TGM1 gene (Arg396Cys). Their parents are carriers, giving future offspring a 25% risk of inheriting the condition. Acitretin therapy at 0.2 mg/kg/day, combined with topical keratolytics, led to significant improvement in symptoms and quality of life within four weeks.

Accurate diagnosis of ichthyosiform disorders requires thorough clinical documentation, family history, physical examination, and genetic findings. Effective management of lamellar ichthyosis needs a multidisciplinary approach, focusing on improving quality of life by addressing physical discomfort and social challenges. Genetic testing, especially Whole Exome Sequencing (WES), is crucial for precise diagnosis, genetic counseling, and informed family planning.

Bullous pemphigoid (BP) is the most common autoimmune blistering disorder in the elderly but is rare in children. Pediatric BP often presents with dramatic features, including eczematous plaques and tense bullae, accompanied by intense pruritus and occasional mucosal involvement. Despite its rarity, BP should be considered in differential diagnoses due to its varied presentations.

An 18-year-old Filipino male presented with intermittent fever followed by multiple erythematous pruritic plaques on his extremities, which later spread to the head and trunk. Generalized tense vesicles and bullae developed on top of existing plaques, accompanied by severe pruritus. Nikolsky and Asboe-Hansen signs were negative. Lesions eventually covered the entire body, including the oral mucosa. Self-medication with herbal concoctions worsened the condition, causing erosion and plaque thickening. Lab tests showed leukocytosis with eosinophilia and extremely elevated serum IgE level. Histopathology revealed subepidermal split with eosinophils, and direct immunofluorescence confirmed BP with 1+ IgG and 2+C3 deposits in the basement membrane zone. Anti-BP180 ELISA was positive. The patient was treated with intravenous hydrocortisone, then transitioned to oral prednisone (40 mg daily, tapered), leading to complete resolution of lesions with no recurrence.

Pediatric bullous pemphigoid, rare in late childhood, mirrors adult cases but with more acral distribution and mucosal involvement. Elevated IgE levels may correlate with disease activity, prompting further study of risk factors and triggers. A collaborative approach is crucial for managing physical and social challenges, improving quality of life.

Hansen’s disease (HD), or leprosy, is a chronic infectious disease caused by Mycobacterium leprae. It remains a public health concern in tropical regions like the Philippines. HD can present with a wide range of clinical manifestations and is often misdiagnosed, particularly as autoimmune disorders. This case report discusses a 20-year-old Filipino female initially misdiagnosed with Raynaud’s phenomenon, suspected to be due to an autoimmune condition.

Five years prior to her current presentation, the patient developed progressive swelling of her hands and feet, temperature-induced color changes, and facial erythema. Initial laboratory tests showed anemia, positive antinuclear antibody (ANA), and elevated complement (C3), suggesting a possible autoimmune disorder. A subsequent skin biopsy confirmed lepromatous leprosy with a bacillary index of 6+. Positive anticardiolipin and anti-beta2 glycoprotein 1 antibodies indicated a probable diagnosis of antiphospholipid syndrome (APS). These APS-like findings were thought to result from leprosy reactions and associated immune dysregulation. Due to rifampicin- and dapsone-induced hemolysis, the patient was treated with clofazimine, ofloxacin, clarithromycin, and oral steroids, resulting in clinical improvement after 12 months. Further hematologic evaluation was ongoing, as she was referred for blood dyscrasia.

Leprosy can mimic autoimmune diseases, as demonstrated by this case. Raynaud’s phenomenon and APS-like features may arise from immune dysregulation caused by chronic infection and leprosy reactions. The case highlights the complexity of diagnosing leprosy with autoimmune-like manifestations and emphasizes the importance of early diagnosis and tailored treatment to prevent complications from multisystem involvement.

Introduction: Extramammary Paget’s disease (EMPD) is a rare cutaneous slow growing tumor seen in areas rich in apocrine glands such as the anogenital region while ectopic EMPD is defined as EMPD arising on non-apocrine areas. The pigmented variant of EMPD is a very rare finding, with only a few reported cases, and can be misdiagnosed as melanoma. Case report: We report a case of a 74-year-old woman who presented with a four-year history of pruritic, non- healing erythematous plaques located on the right axilla and left lower abdomen. Histopathology revealed acanthotic epidermis with atypical keratinocytes that was negative for anti S-100 and Melan-A and was positive for carcinoembryonic antigen (CEA), cytokeratin (CK), CK 7 and epithelial membrane antigen (EMA). Patient was managed as pigmented and ectopic variant of extramammary Paget’s disease. Several tests and imaging were done to rule out malignancy. Wide excision with axillary node dissection, bilateral inguinal node dissection, frozen section biopsy and reconstruction using right pectoralis major musculocutaneous flap, split thickness skin graft with left inguinohypogastric drain were done by reconstructive surgery. Frozen section biopsy was negative for S-100, MELAN-A and HMB-45, ruling out malignant melanoma. Patient followed up every month for 6 months after the procedure with no recurrence and lymphadenopathy. Conclusion This case emphasizes that extramammary Paget’s disease is not a preventable disease and early diagnosis is the key to a favorable diagnosis. Any unilateral eczematous lesion that does not respond to an appropriate course of topical treatment warrants a skin biopsy.

Introduction: Acne vulgaris is a common dermatologic disorder caused by follicular epidermal hyperproliferation, excess se- bum production, inflammation, and Cutibacterium acnes (C. acnes). The mangosteen fruit rind contains large amount of xantho- nes, which has high antimicrobial activity against C. acnes. Objectives: To compare the efficacy and safety of mangosteen 1% extract gel versus benzoyl peroxide (BPO) 5% gel in the treat- ment of mild to moderate acne vulgaris. Methods A total of 60 participants with mild to moderate acne or a rating of 2 or 3 in the Investigator’s Global Assessment (IGA) for acne were randomized to receive either mangosteen 1% extract gel or BPO 5% gel applied on the face twice daily over an 8-week period. Primary outcomes measured in the study were clinical remission graded as “clear” or “almost clear” (rating of 0 or 1) based on the IGA and any adverse reaction.
