Tinea incognito is a dermatophyte fungal infection when the clinical picture becomes unclear due to inappropriate treatment, which is usually caused by the use of topical steroids in cases of skin infections. A 46-year-old woman came with complaints of itchy reddish patches all over her body, experienced for 2 years. The itching worsened when consuming anchovies. The patient said she often took medication bought from a pharmacy without a doctor's prescription, the patient took methylprednisolone tablets and ointment. The itching complaint improved, but after stopping taking the medication, the itching complaint increased, and the patches widened. The patches first appeared on the right leg, initially resembling prickly heat spots then widened and spread to other parts of the body. Currently, the patches appear red in the shape of a ring with a clearer center. The patches were found on the face, neck, chest, abdomen, back, buttocks, left hand, and left foot. The patient noticed within a few months after taking the medication that her body was swollen, her weight increased, and her face looked rounder. A 20% KOH examination found hyphae and spores. Thus, the patient was diagnosed with Tinea Incognito caused by long-term topical steroid use. The patient was prescribed antifungal therapy with Ketoconazole 200 mg tablets once daily and Ketoconazole cream twice daily.

Hyperkeratotic hand dermatitis (HHD) is a chronic hand eczema subtype marked by thick hyperkeratotic plaques, painful fissures, and minimal erythema or vesiculation.It is diagnostically challenging due to overlap with palmoplantar psoriasis and keratoderma and is strongly linked to repeated irritant exposure in wet work. A 60-year-old male taro leaf farmer presented with itching and burning on the palms and backs of both hands, spreading to the forearms for 2–3 weeks. Examination revealed papules, hyperpigmented plaques, erythematous macules, irregular scaling, and about 1 cm palmar fissures on both hands. The working diagnosis was chronic hyperkeratotic hand dermatitis. Initial treatment included oral cetirizine, topical betamethasone valerate, and Vaseline gel, plus education on using long rubber gloves at work. HHD results from skin barrier dysfunction and keratinocyte hyperproliferation caused by repeated irritant exposure. In this case, exposure to taro leaves and prolonged rubber glove use likely maintained irritation and occlusion. Differential diagnoses include palmoplantar psoriasis, contact dermatitis, and tinea manuum. Management involves potent corticosteroids, antihistamines, occlusive emollients, and occupational modifications such as replacing gloves and limiting occlusion time. Identifying occupational factors in HHD is essential. Effective management requires combined topical therapy, symptom control, and strict workplace modifications, along with patient education and allergy screening if needed.

Amyloidosis is a term for various groups of diseases with lots of amyloid protein in organs and/or tissues, causing disease. In this condition, amyloid protein is deposited in the dermis layer of the skin which is called lichen amyloidosis. Lichen amyloidosis is the most common type of cutaneous amyloidosis. The prevalence of cutaneous amyloidosis is relatively rare, only 0.2-0.3%. It is chronic in nature which usually appears later in life. This article discusses a case of a 39-year-old female patient who came with complaints of spots on both sides accompanied by itching. These complaints have been experienced since ± 2 years ago and are felt to be getting worse in the last few months. Previously the patient had used a type of topical medication obtained from the local puskesmas, but there was no improvement. Examination of the general status found the general condition of the patient looked moderately ill, conscious awareness, vital signs within normal limits. Dermatological status obtained efflorescence in the form of macules to multiple papules with hyperpigmentation, well defined, discrete available, accompanied by scaling and lichenification. Patients were treated with oral corticosteroids (methylprednisolone), topical corticosteroids (desoximethasone) and salicylic acid. Patients are also educated to avoid scratching and rubbing on the lesions. The patient showed thinning lesions after 7 days of therapy.
