Cellular Digital Fibroma: A Comprehensive Review of a CD34-Positive Acral Lesion of the Distal Fingers and Toes

A retrospective study on the clinical features of skin lesions in Chinese acquired digital fibrokeratoma patients

BACKGROUND

Acquired digital fibrokeratoma (ADFK) is an uncommon benign fibro-epithelioma, which is rarely reported in China.

AIMS

To analysis the clinical features of ADFK in Chinese people from current cases.

METHODS

From December 2019 to October 2021, there were 21 patients diagnosed with ADFK, we made a retrospective analysis on the clinical features of skin lesions in them. To summarize the clinical morphology, location, and surgical follow-up of ADFK.

RESULTS

We concluded that ADFK is more common in females than males on the hands (7:3), while the male-to-female ratio is largely the same in feet (6:5). It occurs more frequently on the third finger (60%) and first toe (45.5%). As to clinical morphology, it is typically rod-shaped (52.4%), followed by dome-shaped (42.8%) and wart-shaped (4.8%). It is typically dome-shaped on the hands (80%) and rod-shaped on the feet (81.8%). In terms of location on the fingers (toes), such skin lesions are most common at the proximal nail fold (52.4%), which can also occur at the nail matrix (14.3%), periungual area (23.8%), and subungual area (9.5%). Nevertheless, this ratio also varies on the hands and feet. All patients got surgical excision of the skin lesion, who were followed up for 6-12 months, without recurrence.

CONCLUSIONS

Most ADFKs are associated with trauma, whose clinical features are related to location and gender. ADFKs on the hands are different from those on the feet regarding clinical morphology and location on fingers (toes), and surgery is effective in treating this condition.

Acquired fibrokeratoma: A retrospective study in a tertiary centre in South India

Background:

Acquired fibrokeratoma (AFK) is an uncommon, sporadic, benign, acquired, slow-growing dermo-epidermal tumour.

Aims and Objectives:

The purpose of this study was to summarize the demographic, clinical characteristics and treatment outcomes of patients with AFK in a tertiary care centre in South India.

Methods:

We evaluated the records of 26 patients with AFK who were diagnosed and treated in our centre between January 2017 and December 2021. The retrospective data related to age, sex, occupation, consistency, duration of lesions, history of trauma, anatomical site, morphological appearance, histopathological type, treatment provided and recurrence were taken into account and analysed.

Results:

Of the 26 patients, there were 21 males and 5 females. Fingers (n = 23) were the most common site involved, followed by toes (n = 2) and palm (n = 1). A total of 18 patients had finger-like projected lesions and eight patients had dome-shaped lesions. In histopathology, Type I AFK type was observed in 16 cases and Type II in 10 cases.

Conclusion:

We believe that our study would contribute by providing the clinical, histopathology and treatment outcomes of this uncommon dermo-epidermal tumour. The frequency of this condition is often underestimated as it is misdiagnosed for many other dermatological conditions.
