Café-au-lait macules (CALMs) present as benign hyperpigmented, well-circumscribed spots on the skin for which many patients seek treatment for aesthetic reasons. The objective of this study is to report our experience in treating CALMs using a picosecond 532-nm neodymium-doped yttrium aluminium garnet (PS 532 nm) laser. This is a retrospective case series of 16 patients with CALMs who were treated by a PS 532-nm laser (1-4 treatments, 4-8 weeks apart). Response as seen on clinical photographs was assessed by two independent dermatologists and graded on a scale of 0 (exacerbation) to 5 (95-100% improvement)...

Malignant peripheral nerve sheath tumor is a rare tumor occurring in 5%-10% of all malignant soft tissues sarcomas and triton tumor arising from neurofibromatosis type 1 (NF-1) is even rarer with associated high rate of mortality. No case of triton tumor has been reported in Nigeria to the best of our knowledge. We seek to report a case of lately detected retroperitoneal triton tumor presenting in a 12-year-old Nigerian child who was brought with bilateral lower limb weaknesses, weight loss, and a right lumbar mass...

Target antigens in idiopathic membranous nephropathy (MN) include the phospholipase A2 receptor (PLA2R), and in some cases, the thrombospondin type 1 domain-containing 7A (THSD7A). A notable phenomenon is the high rate of cancer (reported to be as high as 20%) in patients with THSD7A-associated MN. Neurofibromatosis type 1 (NF1) is an autosomal dominant disease caused by NF1 gene mutation, and clinically characterized by multiple cutaneous neurofibromas and café-au-lait spots. In this article, we report a patient with NF1 who developed THSD7A-associated MN when the NF1 skin lesions deteriorated...

Neurofibromatosis type 1 (NF1) or Von Recklinghausen disease manifests as cutaneous café-au-lait spots and neurofibromas. It is one of the most common autosomal dominant genetic diseases. It is extremely variable in its individual manifestation. Cutaneous and neurologic symptoms are the most common manifestations but it can also affect other organs including eyes, bones and other areas. Lisch nodules are the most common ocular manifestations in NF-1. They are asymptomatic small pigmented iris tumors (iris hamartomas) which can help suggest the diagnosis of NF1 as they are characteristic of this disease and mostly occur in adult patients...

Punctate leukoderma presents as numerous, distinct, round or oval depigmented spots. Recently, laser therapy-induced punctate leukoderma associated with various Q-switched laser and carbon dioxide laser have been reported. A 25-year-old man presented with numerous, discrete, round, confetti-like, depigmented macules on his left neck. He had undergone 3 sessions of 532-nm Q-switched Neodymium: Yttrium-Aluminum-Garnet laser treatment for café-au-lait macules three years ago. After the last laser treatment session, the punctate leukoderma had been developed...

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder characterized by the appearance of cafe au lait spots, neurofibromas and Lisch nodules. There is an established link between NF1 and the development of breast cancer in women; however, due to the rarity of both NF1 and male breast cancer, the same link has yet to be elucidated in men. The concurrent presentation of NF1 and male breast cancer is a very rare phenomenon with only a handful of case descriptions in the literature. To the best of our knowledge, there have only been four other reported cases of NF1 and male breast cancer before ours...

BACKGROUND: Neurofibromatosis type 1 (NF1) is an autosomally dominant inherited disorder characterized by multiple pigmented skin spots (café-au-lait spots) and neurofibroma. NF1 is associated with a wide variety of benign or malignant tumors. We report a NF1 patient who received surgical treatment for rectal carcinoma and multifocal small intestinal gastrointestinal stromal tumors (GISTs). CASE PRESENTATION: A 70-year-old female patient with NF1 was referred to our hospital after a positive fecal occult blood test...

Neurofibromatosis type I (NF1) microdeletion syndrome, which is present in 4-11% of NF1 patients, is associated with a severe phenotype as it is caused by the deletion of NF1 and other genes in the 17q11.2 region. The variable expressivity of the disease makes it challenging to establish genotype-phenotype correlations, which also affects prognosis and counselling. We here describe a 3-year-old NF1 patient with an atypical deletion and a complex phenotype. The patient showed overgrowth, café au lait spots, inguinal freckling, and neurological abnormalities...

Café-au-lait macules (CALMs) are light to dark brown macules or patches of increased melanin concentration found along the dermoepidermal junction. Although many attempts to treat CALMs using various kinds of laser/light-based devices have been reported, CALMs remain refractory thereto with high recurrence rates. In this case series, we describe four patients with idiopathic CALMs that were effectively and safely treated with a non-ablative, high-fluenced, Q-switched (QS), 1,064-nm neodymium:yttrium aluminum garnet (Nd:YAG) laser...

McCune-Albright syndrome (MAS) is a rare disease defined by the triad of polyostotic fibrous dysplasia of bone, café-au-lait skin spots, and precocious puberty. No available treatment is effective in changing the course of fibrous dysplasia of bone, but symptomatic patients require therapeutic support to reduce bone pain and prevent fractures and deformities. We report the case of a 27-year-old woman with MAS and severe fibrous dysplasia. She was diagnosed with MAS at 4 years of age and, during follow-up, she had multiple pathological fractures and bone pain refractory to treatment with bisphosphonates, tricyclic antidepressants, and opioids...

Ossifying subperiosteal haematoma is an exceedingly rare manifestation of Neurofibromatosis type 1 (NF-1). We report an interesting case of plexiform neurofibroma causing a rapidly growing tibial mass as a result of subperiosteal haemorrhage, in an 11-year-old girl with previously undiagnosed NF-1. This reflects a precursor of the more mature periosteal ossification seen in cases traditionally termed "subperiosteal cysts". A previously well young girl was referred by her general practitioner with an increasingly large, mildly tender, soft lump on the anterior aspect of her right tibia...

Neurofibroma, a benign peripheral nerve sheath tumor, usually appears together with café-au-lait spots, iris nodules, and other tumors within the scope of neurofibromatosis von Recklinghausen type 1 tumors. A solitary neurofibroma of the eyelid is relatively rare. In this case report, we present a 39-year-old woman who had a lesion on the eyelid crease, previously treated as a chalazion. Due to persistent wound crusting, the lesion was excised above the tarsus. Pathological examination revealed a solitary neurofibroma...

BACKGROUND: Bilateral adrenalectomy is performed in cases with infantile-onset Cushing syndrome due to bilateral adrenal hyperplasia in McCune-Albright syndrome (MAS) because severe Cushing syndrome with heart failure and liver dysfunction can have a lethal outcome. This procedure can completely ameliorate hypercortisolism, although lifetime steroid replacement therapy and steps to prevent adrenal crisis are necessary. Recently, the efficacy of unilateral adrenalectomy has been reported in adult cases of bilateral macronodular adrenal hyperplasia, but there is no consensus regarding the appropriate surgical treatment for bilateral adrenal hyperplasia in MAS...

An 8-month-old Caucasian infant with neurofibromatosis type 1 presented with a congenital plexiform neurofibroma and multiple café au lait spots. A pale area surrounded one of the café au lait spots located on the left gluteus in the area of dermal melanocytosis. This halolike phenomenon results from the disappearance of the Mongolian spot around the café au lait spots, revealing normal pigmented skin. This sign has been described rarely in the literature and the pathogenic mechanism is unclear.

Constitutional mismatch repair deficiency (CMMRD) is a rare, recessively inherited childhood cancer predisposition syndrome caused by biallelic germline mutations in one of the mismatch repair genes. The CMMRD phenotype overlaps with that of neurofibromatosis type 1 (NF1), since many patients have multiple café-au-lait macules (CALM) and other NF1 signs, but no germline NF1 mutations. We report of a case of a healthy 6-year-old girl who fulfilled the diagnostic criteria of NF1 with >6 CALM and freckling...

Constitutional mismatch repair deficiency (CMMRD), a variant of Lynch syndrome, is a rare disease characterized by café-au-lait spots, oligopolyposis, glioblastoma and lymphoma. A 24-year-old male, under surveillance for CMMRD, developed Crohn's ileitis after total colectomy with end ileostomy for colorectal cancer and failed to respond to oral corticosteroids. The patient underwent induction and maintenance of remission with vedolizumab infusions. We report the first patient with CMMRD developing Crohn's disease...

BACKGROUND/AIM: The McCune-Albright syndrome (MAS) is a potentially severe disorder hallmarked by fibrous bone dysplasia, café-au-lait skin spots, and endocrine hyperfunction. It is caused by postzygotic activating mutations at the R201 codon of the GNAS gene, leading to a state of somatic mosaicism. Our aim was to improve the mutation detection rate and to quantify the presence of R201 GNAS mutations in different DNA samples from MAS patients. METHODS: Real-time COLD- and MAMA-PCR TaqMan techniques were combined to search for R201 mutations in the DNA of blood or affected tissues from 16 previously molecularly characterized MAS patients, from a further 84 subjects with MAS signs who were R201 negative at RFLP analysis, and from 36 controls...
