Piloleiomyomas in multiple cutaneous and uterine leiomyoma syndrome (hereditary leiomyomatosis and renal cell cancer or Reed syndrome)
Multiple cutaneous and uterine leiomyoma (MCL), or Reed syndrome is an uncommon condition that includes cutaneous piloleiomyomas and internal neoplasms of the uterus and kidney. Clinical findings include clusters of variably-painful, skin-colored-to-red-brown papules. Genetic testing shows germline mutations in the gene encoding fumarate hydratase. We describe a patient with MCL who presented with subtle cutaneous findings. We believe it is important that dermatologists consider a diagnosis of MCL when presented with patients with small painful dermal papules

Multiple eruptive dermatofibromas
We report a 34 year-old woman with psoriasis, systemic lupus erythematosus (SLE), and recent anti-TNFa therapy, who presented with multiple, eruptive dermatofibromas (MEDF). Although the pathogenesis of MEDF remains unknown, there is substantial evidence that this phenomenon represents an aberrant immune response. Like the more common presentation of solitary dermatofibromas, these lesions are benign, and no treatment is required. However, MEDF is increasingly recognized as a sign of immune dysregulation and an appropriate work-up should be initiated to identify an underlying cause in patients without a known trigger

Mycobacterium avium complex infection
We report the case of a 30-year-old woman with a three-year history of papules, nodules, and multiple ulcers of the left lower extremity. A skin biopsy specimen showed dermal fibrosis and patchy granulomatous inflammation in the upper-to-mid dermis that was associated with a perivascular, lymphohistiocytic infiltrate along with granulomas and necrosis in the subcutaneous fat. Tissue culture showed Mycobacterium avium complex infection. Clinical manifestations of cutaneous nontuberculous mycobacterial infections are discussed as well as their potential association with pedicures

Nodular amyloidosis
Nodular amyloidosis is the rarest form of primary cutaneous amyloidosis. We report the case of a 74-year-old woman with an eight-year history of asymptomatic, hyperpigmented plaques on the pretibial areas. A skin biopsy specimen showed deposits of amorphous eosinophilic material that extended throughout the dermis with apple-green birefringence with a Congo-red stain, which established a diagnosis of nodular amyloidosis. Patients with nodular amyloidosis should be evaluated for systemic disease and followed appropriately due to a small risk of progression to systemic amyloidosis

Benign familial pemphigus ( Hailey-Hailey disease)
A 56-year-old man presented with a 15-year history of scaly red plaques on the trunk and axillae. Skin biopsy was consistent with Hailey-Hailey disease. His condition was refractory to multiple therapies, which included topical and oral antibiotics and topical, intralesional, and oral glucocorticoids. Treatment with subcutaneous botulinum toxin type A at the axillae and on the back led to a nearly complete resolution of plaques in those areas. Botulinum toxin type A should be considered in patients with extensive Hailey-Hailey disease who are fail traditional therapies

Lupus miliaris disseminatus faciei
Lupus miliaris disseminatus faciei (LMDF) is a rare, inflammatory condition, which is characterized by red-brown and yellow-brown papules on the face, with characteristic involvement of the eyelids and with histopathologic findings of suppurative and granulomatous folliculitis and dermatitis. The etiology of this disease is not known, but retinoids, anti-inflammatory, immunosuppressive, and antimicrobial medications are utilized to treat the condition with variable results. We present the case of a patient with LMDF that has thus far been refractory to treatment
