Treatment for multiple periorbital eccrine hidrocystomas: botulinum toxin A
Hidrocystomas are relatively common cystic lesions that can display either apocrine or eccrine differentiation. While numerous treatment modalities exist for solitary hidrocystomas including simple excision, electrodesiccation, and CO2 laser, treatment of multiple hidrocystomas can be challenging. A 38-year-old, black female with a 23-year history of multiple periorbital cystic nodules presented to the clinic with the complaint of lesions that were increasing in size and number. Prior treatment included excision resulting in scarring without significant clinical improvement. Initially, incision and drainage was performed with flattening of the cysts; however, the cystic nodules refilled to baseline by 6 weeks. Subsequently, intralesional botulinum toxin type A was offered as an alternate therapy in conjunction with incision and drainage. The patient reported sustained flattening of the lesions at both 1-month and 4-month follow-up appointments. Intralesional botulinum toxin A offers a novel treatment for patients with multiple hidrocystomas that have failed other therapies

Lichen planus pigmentosus-inversus involving the post-auricular sulci
Lichen planus pigmentosus-inversus is rare with only twenty patients (including our patient) formally described in the literature. The reported twenty patients with lichen planus pigmentosus-inversus include eight men and twelve women with ages ranging from 25–84 years (average age of 55.3). Twelve were Caucasian, five were Asian, one was Hispanic and two were of unknown ethnicity. Seventeen out of twenty patients had lesions in the axillae and mild pruritus was present in eight patients. Our patient is the first patient reported to have post-auricular sulcus involvement

Pink nodule of the chin: an unusual presentation of metastatic carcinoma
Renal cell carcinoma (RCC) is the most lethal urological tumor, often because it is widely metastasized at the time of diagnosis. There are reports of cutaneous metastases, most commonly to the head and neck, presenting late after RCC is diagnosed. This case presentation explores a 45-year old female patient with a growing skin lesion on her chin, previously treated as an epidermoid cyst before presenting to dermatology clinic. We present a case of cutaneous metastatic clear cell renal cell carcinoma presenting 7 years after initial diagnosis

Microcystic Adnexal Carcinoma of the scalp in an african-american male
Microcystic adnexal carcinoma (MAC) is a rare adnexal neoplasm that typically presents in Caucasians. We report a rare case of MAC in a 68 year old African American male that presented as a large asymptomatic scalp mass. The clinical and histologic features of MAC are discussed. A summary of all reported cases of MAC in African American patients is presented, and treatment options are discussed
