“…The diagnosis of PA is primarily clinical [1]. Dermoscopy aids in the visualization of asbestos-like scales and polytrichia resulting from matting of hair [7]. However, identification of the underlying condition may require a potassium hydroxide mount of hair and skin scrapings, fungal culture, or scalp biopsy [1].…”

Introduction: Pityriasis amiantacea (PA) is a rare presentation characterized by the presence of extensive adherent scaling that tightly encircles and affixes tufts of hairs secondary to inflammatory or infectious dermatoses. However, the occurrence of PA as a consequence of leukaemia cutis has not been previously reported. Case Report: A 32-year-old man with B-cell acute lymphoblastic leukaemia (B-ALL) presented with severe scalp scaling and hair loss for 2 months. Examination revealed extensive, tightly adherent scales encircling and binding down hairs, along with haemorrhagic crusts. Skin examination showed nontender, partially blanchable papules forming ill-defined plaques, giving a cobblestone appearance. Trichoscopy revealed white crusts, tufting, and micro-haemorrhages. Scalp biopsy confirmed precursor B-ALL infiltration. He was diagnosed with PA with secondary cutis verticis gyrata due to leukaemia cutis and referred to a haemato-oncologist for further management. Discussion: Leukaemia cutis is a rare condition where leukaemia cells infiltrate the skin, often associated with acute myeloid leukaemia and ALL. It can lead to secondary verticis gyrata. The co-occurrence of PA and cutis verticis gyrata is rare and previously unreported, highlighting the need for increased awareness among clinicians.

As tinea capitis rarely affects infants, early trichoscopic diagnosis facilitates timely institution of appropriate therapy. We report a 10-month-old female presenting with mixed pattern tinea capitis and coexisting tinea faciei wherein trichoscopy showed perifollicular scaling, comma hair, corkscrew hair, and horse-shoe hair. Case 2 was a 3-month-old female with gray patch tinea capitis, corroborated by the presence of perifollicular scaling, comma hair, corkscrew hair, and prominent telangiectasia on trichoscopy. Both cases were successfully treated with tablet fluconazole (5 mg/kg) for 6–8 weeks.

“…There are also huge, golden or silvery scales that enclose and bind hair tufts and seem like asbestos (Figure 3) These typical scales have been called amiante or asbestos, as they are said to resemble white or grey fibrous minerals as in Pityriasis amiantacea (PA) which is typically considered to be a reactive condition to several inflammatory diseases, which may affect the scalp, mainly including psoriasis, atopic dermatitis and seborrheic dermatitis, lichen planus, lichen simplex chronicus, superficial fungal or pyogenic infection [15,16] . Under a microscope, scale crusts that resemble amianth or asbestos can be seen sticking to multiple hair shafts in pityriasis amaintacea [17] So that a precise diagnosis may be made, a mucocutaneous examination can be carefully aimed to clarify the following:  Typical psoriasis symptoms include Auspitz's sign, silvery-white scales, and oil-drop indications.…”

Scalp scaling is a frequent and persistent issue that causes a lot of pain, discomfort, and social stigma. Scaling or flaking of the scalp simply denotes a higher rate of epidermal cell turnover. The scalp may be affected locally or diffusely. Although it is frequently asymptomatic, more severe cases may result in pruritus. Scaling may develop as a result of dry scalp and the vulnerability of the skin's outermost layer, variation in sebaceous gland secretion as in seborrheic dermatitis, immune mediated in which activated T cells penetrate the dermis and trigger cytokines, increasing the development of keratinocytes as in psoriasis, and may be associated with alopecia, a common condition in youngsters and frequently connected to tinea capitis. Another indicator of atopic dermatitis is scaling on the scalp. Scaling of the scalp may be present in around half of all children with atopic dermatitis, according to studies of infants 0 to 6 months old and kids from birth to 12 years old. Many medical experts are unaware that scalp scaling is a sign of atopic dermatitis, despite the topic being rarely covered in texts.
