Macular amyloidosis is a common problem seen dermatology out-patient department. Generalized macular amyloidosis presenting with a poikilodermatous appearance is rare. In our case, an 18-year-old male presented with generalized hypopigmented macules with a poikilodermatous appearance of 10-year duration. His developmental milestones were normal with negative family history of similar complaints. Histopathology of hyperpigmented lesions revealed hyperkeratosis and acanthosis of epidermis and hypopigmented lesion showing only hyperkeratosis. Both lesions were showing the deposition of amorphous, hazy material in the tips of papillary dermis with perivascular inflammatory infiltrate. Congo red staining of the amorphous material was positive for amyloid.

Macular amyloidosis is a variant of primary localized cutaneous amyloidosis in which amyloid protein is believed to be derived from keratinocytes. The care of this variant generally focuses on addressing the associated symptoms without the need to assess for underlying disease. However, an increasing number of cases of primary localized cutaneous amyloidosis have been reported in association with systemic diseases, particularly autoimmune diseases.

Background: Macular amyloidosis (MA) could be of cosmetic concern with a significant psychological impact for patients, and its treatment is challenging.
Aim Of The Work: To compare the efficacy and safety of combined fractional CO laser with dimethyl sulfoxide (DMSO) 50% versus fractional CO laser alone in the treatment of macular amyloidosis.
Patients And Methods: Twenty patients with macular amyloidosis were treated with monthly session of fractional CO laser only in one side of the lesion (area A), and fractional laser followed by application of DMSO 50% solution in the other side of the lesion (area B).

Article Synopsis
- * Some skin lesions can be subtle, often categorized as "invisible" dermatoses, like primary macular cutaneous amyloidosis and calciphylaxis, necessitating detailed examination.
- * Certain conditions have significant prognostic implications, indicating potential underlying diseases like monoclonal gammopathies or association with visceral damage, underscoring the importance of clinical-pathological comparison to differentiate between serious conditions.
The effect of topical tranexamic acid with micro-needling and micro-needling alone in treatment of macular amyloidosis.

Article Synopsis
- - The study focused on comparing the effectiveness of combining topical tranexamic acid with micro-needling versus micro-needling alone in treating macular amyloidosis, a skin condition characterized by itchy, pigmented macules.
- - A total of 20 female patients participated, with their skin being treated in two groups over four sessions; results showed improvements in both groups regarding pigmentation and itchiness, but no significant difference was found between the two treatment methods.
- - Ultimately, micro-needling alone was effective in reducing pruritus and pigmentation, while the addition of tranexamic acid did not provide any extra benefits.
