Patients and methods Received 07 August 2018 Revised 10 September 2018 This cross‑sectional study included 105 Egyptian patients (50 female individuals and 55 male Accepted 23 September 2018 individuals) with transfusion‑dependent β‑thalassemia major in the period spanning from June Published 25 March 2020 2017 to February 2018. The study was performed on child and adult patients of β‑thalassemia Menoufia Medical Journal 2020, 33:267–271 who presented to the hematology clinic, Menoufia University hospital. Skin examination of each patient was carried out, and any skin disease present was recorded. Results The main skin disorders that were noticed in decreasing order of frequency were pruritus (34.4%), xerosis (24.8%), urticaria (21.1%), freckles (17.1%), tinea infections (11.6%), pitriasis alba reported in 10.5%, scars (10.5%), hypersensitivity to deferoxamine pump (9.5%), herpes simplex (9.5%), acne vulgaris (8.6%), miliaria (6.7%), contact dermatitis (4.8%). Conclusion Skin diseases were frequent among patients with β‑thalassemia major. The most common skin lesions in our patients were pruritus, xerosis, and hyperpigmentation. Careful skin examination of thalassemia patients is required to provide early diagnosis of dermatological diseases and a better quality of life.

Melano- cytes, which are derived from the neural crest, are unique in that they produce eu-/pheo- melanin pigments in unique membrane-bound organelles termed melanosomes, which can be divided into four stages depending on their degree of maturation. Pigmentation production is determined by three distinct elements: enzymes involved in melanin synthesis, proteins required for melanosome structure, and proteins required for their trafficking and distribution. Many genes are involved in regulating pigmentation at various levels, and mutations in many of them cause pigmentary disorders, which can be classified into three types: hyperpigmen- tation (including melasma), hypopigmentation (including oculocutaneous albinism [OCA]), and mixed hyper-/hypopigmentation (including dyschromatosis symmetrica hereditaria).

    Phacomatosis Spilorosea Versus Phacomatosis Melanorosea

    Acta Dermatovenerologica 2021;30:27-30 Acta Dermatovenerol APA Alpina, Pannonica et Adriatica doi: 10.15570/actaapa.2021.6 Phacomatosis spilorosea versus phacomatosis melanorosea: a critical reappraisal of the worldwide literature with updated classification of phacomatosis pigmentovascularis Daniele Torchia1 ✉ 1Department of Dermatology, James Paget University Hospital, Gorleston-on-Sea, United Kingdom. Abstract Introduction: Phacomatosis pigmentovascularis is a term encompassing a group of disorders characterized by the coexistence of a segmental pigmented nevus of melanocytic origin and segmental capillary nevus. Over the past decades, confusion over the names and definitions of phacomatosis spilorosea, phacomatosis melanorosea, and their defining nevi, as well as of unclassifi- able phacomatosis pigmentovascularis cases, has led to several misplaced diagnoses in published cases. Methods: A systematic and critical review of the worldwide literature on phacomatosis spilorosea and phacomatosis melanorosea was carried out. Results: This study yielded 18 definite instances of phacomatosis spilorosea and 14 of phacomatosis melanorosea, with one and six previously unrecognized cases, respectively. Conclusions: Phacomatosis spilorosea predominantly involves the musculoskeletal system and can be complicated by neuro- logical manifestations. Phacomatosis melanorosea is sometimes associated with ancillary cutaneous lesions, displays a relevant association with vascular malformations of the brain, and in general appears to be a less severe syndrome.

    "Abstract" "comparison of prevalence and number of lentigo, Freckle, melanocytic nevus and other neavus lesions in women with and without melasma" Introduction: Melasma is applied to a pattern of pigmentation seen mainly in women, and may be regarded as a physiological change in pregnancy. the hypermelanosis affects the upper lip, cheeks, forehead and chin and becomes more apparent following sun exposure. Developmental defects or naevoid lesions are circumcribed lesions of the skin and/or neighbouring mucosae, which are not neoplastic. objective: at this stady we studied prevalence and number of lentigo, freckle, melanocytic nevus and other Nevus in women with and without melisma. Methods and materials: in a case- control study 120 women who have melasma (case group) and 120 women who have not melasma (control group) were entered in study. They were matched for age. Subjects were examined by a dermatologist and a questioner was compeleted for every body. lesions diagnosis were done only by clinical sign and observation. collected data were analysed by soft ware of spss. Results: mean age was 29.97 ± 6.6 in case group and 29.7 ± 6.7 in control group. There were no significant difference. Prevalence of freckles was higher in control group [(24.3% versus 4.16%) P<0/001] 64.1% in case group and 16.6% of cintrol group had lentigo. there was significant difference between both group (p<0/001)mean number of lentigo in case group was 25.2 and in control group 8. (P=0.01) Prevalence of melanocytic naevus in control group was lower than case group (96.6% versus 98.3%).There was no significant difference.

There are multiple options for cosmetically treating these trouble areas. Your DCCC provider is able to diagnose the problem and work with you to find the best solution. Solar lentigo (sun spot, liver spot) is the most common benign, sun-induced lesion. A solar lentigo looks like a freckle and is more often seen in fair-skinned people. They appear most commonly on the face, arms, backs of the hands, chest, and shoulders as we age. The term “lentigo maligna”, refers to a lesion that may look similar to a solar lentigo, but is actually a superficial melanoma. If you notice a freckle that looks different than the others, including having a darker & irregular color or increased texture, these could be warning signs and should be evaluated by your dermatology provider. Yearly skin checks are recommended! For the most part, lentigines are a cosmetic concern which many people are interested in having re- moved. The procedures we offer at DCCC include: Excel V laser, Intense Pulsed Light (IPL), or cryo- therapy. -The Excel V laser is an excellent option for treating solar lentigines and may be used safely in people with all skin types.

Some persist and a small number progress to squamous cell carcinoma. For a person with an average of 7.7 lesions, the probability of at least 1 lesion transforming to SCC in a 10-year period is ~10%. All patients diagnosed with AK in the community Except: Who? Immunosuppressed, especially those post transplant AKs induced by phototherapy e.g. PUVA for psoriasis Is there a past or family history of skin cancer or AK? Is the lesion painful? Diagnosis How quickly is it growing? Carefully examine the lesion & the REST of the patient’s skin Features of AK: www.dermnetnz.org/lesions/solar-keratoses Commonly develop on sun exposed sites in older people Forehead, face, back of hands, bald scalp of men, and ladies legs Early lesions may be red patches and produce pin-prick sensation.

E-mail: [email protected] ABSTRACT Pigmented xerodermoid, a rare genodermatosis, presents with clinical features and pathology similar to xeroderma pigmentosum, but at a later age. DNA repair replication is normal, but there is total depression of DNA synthesis after exposure to UV radiation. Two siblings in their teens and a man in his thirties with features of pigmented xerodermoid, e.g. photophobia, freckle-like lesions, keratoses, dryness of skin, and hypo- and hyper-pigmentation, are described. Although classically the onset of pigmented xerodermoid is said to be delayed till third to fourth decade of life, it seems the disease may appear earlier in the tropics. Early diagnosis and management could be life-saving. KEY WORDS: Xeroderma pigmentosum.
