Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous tumour of neuroendocrine cell origin, which can grow rapidly and metastasise early. Localised disease is treated with surgery and radiotherapy. Disease that reaches a more advanced stage can be treated with a variety of different treatment modalities including surgery, radiotherapy, chemotherapy, radionuclide therapy, immunotherapy, and intralesional therapy.

Concurrent multiple primary extramammary Paget's disease (EMPD) is rare. Herein, we present two Chinese cases of concurrent primary EMPD involving both the genitalia and the axilla, and they also had a history of other malignancy.

The COVID-19 pandemic led to a decrease in the number of operating rooms available. Single-stage islanded forehead flaps have emerged as a good alternative to the classic frontal flap helping to diminish the surgical waiting list. We present our case series of 6 patients reconstructed with islanded forehead flaps between February and July 2020. Read More

Rosai-Dorfman-Destombes disease (RDD) is a rare histiocytic disorder affecting lymph nodes as well as extranodal sites. Although cutaneous involvement in RDD is common, primary cutaneous RDD is a distinct and not well-documented entity with unknown aetiology and non-specific clinicopathological features. We report a case of a 57-year-old patient, who presented with an indolent skin nodule in the left sub-nipple area. Read More

Genital keratotic lesions include bowenoid papulosis (BP), which histologically resembles squamous cell carcinoma in situ containing high-risk HPV, condyloma acuminatum (CA) that is a genital wart containing mostly low-risk HPV, and genital seborrheic keratosis (GSK), which is a benign epidermal tumour lacking a clear etiologic relationship with HPV. This study compared HPV genotype distributions among BP, CA and GSK and revealed that BP and GSK were related to high-risk HPV whereas CA was related to low-risk HPV. It is plausible that GSK is a distinct epidermal tumour often related to high-risk HPV rather than merely a senescent form of CA considering the overall discrepancy in the frequency distribution of HPV genotypes along with histopathological differences, and the detection of high-risk HPV in GSK alerts physicians to consider more active treatment and continued follow-ups.

Hyperkeratotic flexural erythema (HKFE), also termed granular parakeratosis (GP), is a rare skin condition thought to be linked to a skin barrier dysfunction process, however the exact cause of this is yet to be determined. Management options are varied, with no consensus on treatment. Several previous reports have recorded successful treatment with amoxycillin-clavulanic acid combination. Read More

Aims: Regular skin examinations for early detection of melanoma are recommended for high-risk individuals, but there is minimal consensus regarding what constitutes 'high-risk'. Melanoma risk prediction models may guide this. We compared two online melanoma risk prediction tools: Victorian Melanoma Service (VMS) and Melanoma Institute Australia (MIA) risk tools; to assess classification differences of patients at high-risk of a first primary melanoma.

Proliferative nodules (PNs) are benign nodular proliferation of melanocytes occurring within congenital melanocytic naevi (CMN). Differential diagnosis between PN and melanoma is challenging for clinicians and pathologists. We describe the case of a 9-month-old boy who developed multiple nodules arising in a medium-sized CMN.

Red Ear Syndrome is an uncommon disorder that can affect all age groups. It is frequently referred to Dermatology as it can present similarly to erythromelalgia. Although the exact pathophysiology is unknown, a common hypothesis suggests a shared pathophysiological background with migraine due to their well-known association. Read More

Background: Epidemiological evidence regarding the course and activity patterns of hidradenitis suppurativa (HS) is yet to be delineated.

Objective: To identify activity patterns of HS throughout the time axis and to outline predictors of recalcitrant disease course.

Methods: A population-based retrospective cohort study was performed to follow patients with HS (n = 4417) throughout the initial 10 years following their diagnosis. Read More
