Diagnosis of Toxic epidermal necrolysis
Toxic epidermal necrolysis, often abbreviated as TEN, is a rare but life-threatening severe skin reaction. It is usually identified through a combination of clinical findings, medication history, and targeted testing rather than by a single definitive bedside sign. The disorder belongs to the spectrum of severe cutaneous adverse reactions and is characterized by extensive death…

Diagnosis of Tinea cruris
Tinea cruris is a superficial fungal infection of the groin and adjacent upper thigh, usually caused by dermatophyte organisms that thrive in warm, moist, and occluded skin. Medical professionals diagnose it by combining the appearance of the rash, the patient’s history, and, when needed, laboratory confirmation. Accurate diagnosis matters because several other skin disorders can…

Diagnosis of Tinea capitis
Tinea capitis is a fungal infection of the scalp and hair shafts caused by dermatophytes, organisms that digest keratin. Because the infection can weaken hair, cause patchy hair loss, and sometimes inflame the scalp, it is often evaluated carefully rather than diagnosed from appearance alone. Medical professionals combine the patient’s history, physical findings, and specific…

Diagnosis of Stevens-Johnson syndrome
Stevens-Johnson syndrome (SJS) is a rare but serious medical emergency that is usually identified by its pattern of rapidly developing skin and mucous membrane injury, often after exposure to a medication or, less commonly, an infection. Diagnosis is primarily clinical, meaning it depends on recognizing the characteristic appearance and timing of the illness rather than…

Diagnosis of Squamous cell carcinoma of the skin
Squamous cell carcinoma of the skin is diagnosed by combining clinical assessment with tissue confirmation. In many cases, a clinician first suspects the condition after seeing a persistent, unusual lesion on sun-exposed skin, but suspicion alone is not enough. Because many benign and malignant skin disorders can look similar at first glance, accurate diagnosis depends…

Diagnosis of Seborrheic dermatitis
Seborrheic dermatitis is usually diagnosed through a clinical evaluation rather than a single definitive laboratory test. A clinician identifies the condition by combining the appearance and distribution of the rash with the patient’s history and by considering alternative diagnoses that can look similar. This matters because seborrheic dermatitis often affects visible, high-friction areas such as…

Diagnosis of Scleroderma
Scleroderma is diagnosed through a combination of clinical observation, laboratory testing, and, in some cases, imaging or tissue examination. The condition is not identified by a single definitive test in most patients. Instead, clinicians look for a pattern of findings that reflects the underlying disease process: abnormal immune activity, damage to small blood vessels, and…
