Malignant acrospiroma (MA) – is rather rare tumor with eccrine ductal and secretory differentiation, including clear cell component. This type of tumor appears more often in elderly people (average male patient age is 51 years, female patient – 55 years). The tumor corresponds to solitary intradermal, exophytic or mixed type node 0.5-2 cm or more in diameter, hemispheric, tight-elastic texture, on wide base, covered with unchanged skin, sometimes with ulcers. Small percent of cases have clear discharge from tumor. Considering the same architecture of malignant nodular hydradenoma and benign analogue, it is difficult to find the difference between them, although undisputed manifestation of malignance is vessel and perineural invasion, lymphogenic metastasis.
The tumor is very aggressive and liable to metastasis. It is important to notice that there are no direct histological and clinical signs, predicting biological behavior of the tumor. Despite chemotherapy, patients with metastasis has fatal outcome vary rapidly. There no proved data of chemotherapy impact on malignant acrospiroma.

Recommendation at discharge
1. Family doctor supervision
2. Control blood analysis in 7-21 days.
3. CT assessment of chest, abdominal cavity and pelvis after 3months:
Complete diagnosis at discharge
Malignant acrospiroma, T2N0M1 stage IV (mts in lungs and liver), condition after non-radical surgery, after 8 cycles of chemotherapy clinical group II.
Patient had positive dynamics after chemotherapy treatment, complete response as per RECIST 1.1. Patient had not complaints.
CT assessment of chest, abdominal cavity and pelvis with IV contrast as of 28 Jun 2017: CT-signs of stable size of thyroid gland left lobe formation, positive dynamics due to disappearance of lesions in lungs, mediastinal lymph nodes, liver lesions. No new lesions.
Patient has fully active lifestyle, and he is under family doctor and oncologist supervision [Figure 1].
